摘要
现代移动通信领域中,数据业务的发展,需要把越来越多的数字信号与传统的语音信号复合起来在信道中传输。如果没有有效的机制,语音信号的传输常常会被数据信号所阻断,而数据信号的时延也会令人无法忍受。该文应用最优化设计理论中惩罚函数的算法,搜索语音与数据在帧中最佳相对位置,使语音传输被阻断的概率和数据排队的延迟达到最小。从而优化了结构,获得最大的吞吐量、提高了TDMA传输系统的性能。
Today the data service in mobile communication is increasing very fast,which leads to the wide application of mixed transmission of audio signals and data signals in the same channel.Without efficient optimization,the mixed transmission will result in frequent interrupt during the normal call or unendurable transfer delay of the data transmission.This chapter describes the application of Penalty Function Method for optimization in TDMA transmission system.With this algorism we search the best relative positions of audio frames and data frames which will reach the minimum probability of the call interrupt and the minimum delay due to the data queue.Then the whole structure is optimized which leads to the maximum throughput to improve the capability of the system.
