BER & SNR Performance of MIMO OFDM with Space-Time Block Coding

摘要

Multi-Input and Multi output-OFDM system which is the merging of two systems, MIMO and OFDM, have more data transmission rate with huge diversity. STBC with MIMO-OFDM has a better performance against the multipath interference including destructive interference which causes fading with less Bit Error rate, coding complexity and more SNR ratio. Created and analyzed a digital prototype of a physical model for estimating the performance of the MIMO-OFDM system with STBC. The analysis carried out here shows that the MIMO-OFDM system along with STBC has better Signal to Noise Power Ratio with less BER than the Non-STBC MIMO-OFDM system.
