A Deep Learning Based Broadcast Approach for Image Semantic Communication over Fading Channels

We consider an image semantic communication system in a time-varying fading Gaussian MIMO channel,with a finite number of channel states.A deep learning-aided broadcast approach scheme is proposed to benefit the adaptive semantic transmission in terms of different channel states.We combine the classic broadcast approach with the image transformer to implement this adaptive joint source and channel coding(JSCC)scheme.Specifically,we utilize the neural network(NN)to jointly optimize the hierarchical image compression and superposition code mapping within this scheme.The learned transformers and codebooks allow recovering of the image with an adaptive quality and low error rate at the receiver side,in each channel state.The simulation results exhibit our proposed scheme can dynamically adapt the coding to the current channel state and outperform some existing intelligent schemes with the fixed coding block.

A CSMA/CA based MAC protocol for hybrid Power-line/Visible-light communication networks:Design and analysis

Hybrid Power-line/Visible-light Communication(HPVC)network has been one of the most promising Cooperative Communication(CC)technologies for constructing Smart Home due to its superior communication reliability and hardware efficiency.Current research on HPVC networks focuses on the performance analysis and optimization of the Physical(PHY)layer,where the Power Line Communication(PLC)component only serves as the backbone to provide power to light Emitting Diode(LED)devices.So designing a Media Access Control(MAC)protocol remains a great challenge because it allows both PLC and Visible Light Communication(VLC)components to operate data transmission,i.e.,to achieve a true HPVC network CC.To solve this problem,we propose a new HPC network MAC protocol(HPVC MAC)based on Carrier Sense Multiple Access/Collision Avoidance(CSMA/CA)by combining IEEE 802.15.7 and IEEE 1901 standards.Firstly,we add an Additional Assistance(AA)layer to provide the channel selection strategies for sensor stations,so that they can complete data transmission on the selected channel via the specified CSMA/CA mechanism,respectively.Based on this,we give a detailed working principle of the HPVC MAC,followed by the construction of a joint analytical model for mathematicalmathematical validation of the HPVC MAC.In the modeling process,the impacts of PHY layer settings(including channel fading types and additive noise feature),CSMA/CA mechanisms of 802.15.7 and 1901,and practical configurations(such as traffic rate,transit buffer size)are comprehensively taken into consideration.Moreover,we prove the proposed analytical model has the solvability.Finally,through extensive simulations,we characterize the HPVC MAC performance under different system parameters and verify the correctness of the corresponding analytical model with an average error rate of 4.62%between the simulation and analytical results.

Aspects of Communicative Approach and Its Application on Language Teaching and Learning in the Setting of China’s University

The ultimate goal of language teaching is to develop students’ communicative competence. However,university English teachers often find it difficult to reach the aim in the English classroom, especially in the skills of listening and speaking.Their efforts in promoting students’ communicative competence are not fully felt by the students.Students also find it discouraging in the course of language learning.Communicative approach,which is an effective method to develop students’ communicative competence in the real life,stimulates the students learning interests and promotes students’ listening and speaking abilities.This paper aims to illustrate the aspects of communicative approach and its application to the foreign language teaching and learning.

A Communicative Approach to College English Grammar Teaching and Learning

In response to the misconception that Communicative Language Teaching means no teaching of grammar,it is argued that grammar is as important as traffic rules for safe and smooth traffic on the road.To achieve appropriate and effective communication,a communicative approach to college grammar teaching and learning is proposed.Both teachers and learners should change their attitudes toward and conceptions about grammar teaching and learning;additionally,teaching grammar in the company of reading and writing helps learners learn and acquire grammar in meaningful contexts.

Evaluation of Communicative Approach in the College English Listening Course

The traditional ways of teaching in China put emphasis on the development of reading and grammar.So students are famous for their high marks in reading and low marks in listening,and lack of communicative competence.To solve this problem,this study introduces Communicative Approach(CA) to the English listening class.In order to investigate the effects of the CA on students' listening abilities further,a 18-week comparative study on two classes is conducted.The data show that students' listening abilities and attitudes in the CA class is significantly higher and more positive than those in the traditional class,which indicates that CA is an effective approach in improving students' listening abilities compared to the traditional approach.

Communicative, Learner-centered Approach in EMP

This paper discusses communicative approaches in order to help the teacher effect an orderly transition from general English teaching to English for specific purposes. Language, considered as a tool of communication, no longer appears as a separate subject but as an aspect of other subjects. What is needed, therefore, is a different orientation to college English teaching and to find out an approach, which departs from what is generally taken. The approach aims at developing skills and ability to use language in the performance of different communicative acts. It is concluded that language teaching is essentially skill developing, variety is the spice of life and practice makes perfect.

THE COMMUNICATIVE APPROACH TO THE TEACHING OF ENGLISH AS A FOREIGN LANGUAGE

1. Introduction In educational theory, as with most things, there exist fashions and trends. Within the field of foreign language teaching the communicative approach is with good reason very fasharable in the west. The name certainly makes it difficult to argue with, who would want to use the ’non-communicative’ approach to teaching a foreign language? The need to communicate in a language is what makes language teaching different from teaching many other subjects. If you study geography, you learn about places, but if you only learn about a language it is not enough.

The Communicative Approach for EFL Writing to College Sophomore English Majors in China

Although English writing teachers paid great energy and time on students' writings in terms of revision of sentence structure, grammar, word choice, spelling and punctuation, students' English writing abilities have been progressed much less than expected. In other words, students' writings are characteristic of plain content, disorder of organization, simple sentence structure, generalized vocabulary, poor grammar. By the method of deduction, combined benefits and weaknesses of product-oriented approach with process-oriented approach, the communicative approach, comes to be applied in EFL writing for sophomore college English majors. Communicative approach by combination of meaningful learning, the anticipation of reward, the intrinsic motivation, the autonomy, language culture connection the communicative principle, the task principle brings much more effective success in writing teaching.
