Abstract

HIPERLAN/2 system integrated with Alamouti technique is presented, where multiple input multiple output system including space time diversity have been employed into HIPERLAN/2 system. This method, noise reduction is applied when the transmitted antennas are closely located to the receive antennas, and they are working in a full-mode duplexing. Several factors for testing the performance of the modified system such as changing the modulation scheme and the feedback accuracy have been considered, the system performance was tested in terms of bit error rate (BER) and the signal to noise ratio (SNR). MATLAB and Simulink are used for simulating and evaluating the suggested system. the performance of the suggested system is mainly depending on the feedback mismatch amount. The modified system performance enhances as the feedback accuracy increases.
