In this project, we will deal with OrthogonalFrequency Division Multiplexing (OFDM) transmissions over block-fading channelusing M-QAM modulation scheme and MRC technique. We investigate the effect ofreceive diversity by using one sending antenna at the transmitter and variousreceiving antennas at the receiver
In wireless communication systems antenna diversity isan important technique to combat multipath effects of fading to improve thesystem performance and to increase the channel capacity. We use maximal ratiocombining (MRC) technique. The performance of MRC for OFDM system is analysedin terms of signal-to-noise ratio (SNR) and bit error rate (BER) probability.
The results have shown that MRC give the performance (SNR) of an OFDM system can be significantly improvedusing MRC. Furthermore, when increasing t
