多输入多输出变换域通信系统设计与研究

Design and Research of a Multiple-input Multiple-output Transform Domain Communication System

传统的变换域通信系统(T ransform D om a in Comm un ication System,TDCS)在获得强抗干扰能力的同时,其传输的有效性差也成为制约其广泛应用的技术瓶颈。通过引入多输入多输出(M u ltip le-inpu tM u ltip le-ou tpu t,M IM O)技术改进收发端天线,提出了一种多输入多输出变换域通信系统(M IM O-TDCS),旨在保持TDCS抗干扰能力的同时,利用空间分集和空间复用改善其性能。对该系统的基本原理、收发信机模型和军事应用作了简要分析和介绍,通过研究表明,M IM O-TDCS是一种可实现的、具有一定研究价值的通信手段。

With the excellent ability of anti-interference, the conventional Transform Domain Communication System （TDCS） is conditioned in extensive application for the low data rates between the transmitter and the receiver. This paper presents a Multiple-input Multiple-output Transform Domain Communication System （MIMO-TDCS） by adding MIMO and V-BLAST receiver architecture to TDCS for improving its performance. The paper introduces the basic principle and function model as well, and analyzes its military application concisely. The analysis shows that the proposed system is a kind of potential communication technique which both has high data rates and strong anti-interference ability.
