SDR DESIGN AND IMPLEMENTATION OF DIFFERENTIAL STBC TRANSMISSION

Multiple-input-multiple-output (MIMO) technology uses multiple antennas and advanced signal processing to increase the communication system capacity, reliability data rate without sacrificing energy consumption or RF bandwidth. In some scenarios, MIMO need be designed knowledge of 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 prototype a DSTBC-based 2 × 1 MISO (multiple-input-single-output) system. The performed by software with MATLAB. This defined radio (SDR) approach allows reconfigurable implementation Differential STBC algorithm tuneable parameters.
