Combined Beamforming with Space Time Frequency Coding for Mimo-OFDM Systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
Multiple antennas can be used in wireless systems to attain good quality of service and high data rate communication. Recently, efficient space-time-frequency (STF) codes have been developed to improve the diversity gain. Performance of multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO–OFDM) system using STF Coding and random beamforming is analysed. Combined beamforming with STF code offers improved performance over STF in term of bit error rates (BER) when compared to existing combined space-time block code (STBC) with beamforming.
