Abstract

The performance of a wireless communication system is analyzed considering multi-carrier OFDM with Multiple- Input-Multiple-Output (MIMO) wireless channel and Space-Time Block Coding (STBC). Bit Error Rate (BER) expression for MIMO-OFDM system without and with STBC is presented considering fading and timing jitter with QPSK, DPSK and DQPSK modulation schemes. The performance results are evaluated without and with rate Â¿ convolution coding with hard decision decoding. The results are presented in terms of BER, power penalty due to fading and coding gain due to error correction coding. It is noticed that there is significant power penalty due to fading and can be reduced by increasing the number of receiving antennas. Among the different modulation schemes QPSK is found to provide the best performance.
