Abstract :
The digital communication using multiple-input multiple-output (MIMO) has considered as one of the most significant technical in modern communications. MIMO has emerged as a hot topic in wireless communications during the last decade. This is due to possible dramatic increases in reliability and capacity as compared to single-antenna solutions. This paper presents a detailed study of diversity coding (Alamouti Code, and Golden code) for MIMO systems. Performance results show that comparison between these codes on the one hand the performance according to their Bit Error Rates (BER) and signal to noise ratio (SNR) by using 4-QAM and 16-QAM modulation schemes are considered over Rayleigh channel for two transmitters and two receivers.
