    This packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder). You should run "Simulation.m" function that include all modules.

  • 多载波扩频通信的Rake接收机理论研究及FPGA实现.rar

    由于移动环境的复杂性,无线信号在发送传输和接收过程中有很明显的衰落现象,特别是在高频无线通信中,多径衰落或频率选择性衰落对无线信号的干扰最为严重。通过分集接收技术,Rake接收机在CDMA移动通信系统中抗多径衰落效果尤为明显。作为一种新颖的多址接入方式,多载波CDMA充分利用了OFDM最优频率利用率以及CDMA的多址和频率分集,且系统容量和抗符号间干扰性能明显优于传统的单载波CDMA。这些特性使得多载波CDMA成为未来的宽带无线通信系统最有希望的候选。 @@ 本文研究了一种多载波扩频通信系统,介绍了其Rake接收机工作原理和设计思想,进行了理论仿真并用FPGA予以实现。 @@ 本文首先介绍了移动通信系统的发展历史以及OFDM和CDMA技术原理,并描述了OFDM和CDMA结合的三种系统(MC-DS-CDMA、MT-CDMA、MC-CDMA)的原理和系统模型;接着,介绍了目前影响移动通信的主要衰落以及Rake接收机基本原理及其作用。多径信号的每路信号都可能含有可以利用的信息,Rake接收机就是通过多个相关接收器接收多径信号中各路信号,通过信道估计和信道补偿消去信道因子的附加相位,并把他们合并在一起,以此来改善信号的信噪比和系统的可靠性;在此基础上,论文提出了一种多载波扩频通信系统的实现方案,并详细介绍了其Rake接收机实现原理,给出了最大比合并时各种分径数目下系统误码率的仿真图;最后介绍了此方案中Rake接收机的FPGA硬件实现设计方案及其系统 测试结果。@@ 仿真结果显示出随着分集径数的增加,系统的误码率显著降低。表明Rake接收机抗多径衰落效果显著,且在多载波CDMA系统中其分集效果更好,实现相对简单。最终Rake接收机的FPGA实现结果同理论仿真一致,时序通过,资源耗费不大,具有较大的实用价值。 @@关键词:多载波扩频通信,CDMA,Rake接收机,FPGA
