Abstract :

The evaluation of  AF (Amplify and Forward) MIMO (Multiple Input Multiple Output) incremental relay wireless system is carried out and compared against the performance of a  DF (Decode and Forward) MIMO relay wireless system. The encoding scheme used in MIMO relay is  Alamouti coding and  decoding is done by a modified Maximum Likelihood (ML) decoder. The plots of  bit error rate (BER) versus signal to noise ratio (SNR)  are simulated  by incorporating Rayleigh fading condition in the presence of additive white Gaussian noise (AWGN). The performances of the two incremental relaying schemes is evaluated and  better spectral efficiency is achieved.
