Enhanced Space Time Block Coded Spatial Modulation with Space-Time Trellis Codes For Sensing MIMO Technique
Journal Title: The International Journal of Technological Exploration and Learning - Year 2013, Vol 2, Issue 6
Abstract
Multiple-input multiple-output systems have better performance under fading channels than single-input singleoutput (SISO) systems because of the huge capacity and reliability gains promised even in worst fading environment. This project presents the behavior of MIMO systems using STBC-SM scheme over Rayleigh Fading channel environments. MIMO transmission systems are investigated in terms of Bit Error Rate (BER) and Signal-to-Noise Ratio (SNR) performance. BER vs SNR performance of STBC-SM systems are simulated for different number of transmitters using BPSK , QPSK and QAM modulation techniques and various equalization techniques such as Zero Forcing (ZF), Minimum Mean Square Error (MMSE) and Maximum Likelihood (ML). Results show the different error rate performance and channel capacity of a MIMO system using STTC scheme using QPSK modulation.
