Abstract

Multiple-input-multiple-output (MIMO) technology uses multiple antennas and advanced signal processing to increase the communication system capacity, reliability and data rate without sacrificing energy consumption or RF bandwidth. In some scenarios, the MIMO communication system need to be designed without knowledge of the channel state information. One possible solution is differential space–time block coding (DSTBC). Ettus USRPs (Universal Software Radio Peripherals) are used in this research work to prototype a DSTBC-based 2 × 1 MISO (multiple-input-single-output) communication system. The signal processing is performed by software with MATLAB. This software defined radio (SDR) approach allows a reconfigurable implementation of the Differential STBC algorithm with tuneable parameters.
差分STBC传输的SDR设计与实现
多输入多输出(MIMO)技术使用多个天线和先进的信号处理来提高通信系统的容量、可靠性和数据速率,而不牺牲能量消耗或射频带宽。在某些情况下,需要在不知道信道状态信息的情况下设计MIMO通信系统。一种可能的解决方案是差分空时分组编码(DSTBC)。Ettus usrp(通用软件无线电外设)在本研究工作中用于基于dstbc的2 × 1 MISO(多输入单输出)通信系统的原型。用MATLAB软件对信号进行处理。这种软件定义无线电(SDR)方法允许具有可调参数的差分STBC算法的可重构实现。
