Abstract

Abstract: This paper presents and implements a despreading receiver structure on FPGA for the Time-Frequency-Domain Spread Multicarrier DS-CDMA（TF/MC DS-CDMA） communication system.The performance result，simulated by IT++ library of classes，on Rayleigh-flat-fading channel，eventually verifies the advantage of TF/MC DS-CDMA system over other MC-CDMA structures.

Key words: 2D-spread-spectrum, multi-carrier, Code Division Multiple Access（CDMA）, software radio, Rayleigh channel

摘要： 针对一种新型的时频二维联合扩频多载波码分多址（TF/MC DS-CDMA）通信系统，提出了其解扩接收机的结构，在FPGA上进行了实现。利用面向通信系统的仿真类库IT++，对所提出的TF/MC DS-CDMA系统接收机在瑞利平坦衰落信道下的性能进行了仿真分析，验证了TF/MC DS-CDMA结构相对于其他MC-CDMA（多载波码分多址）结构所具有的优越性。
