Abstract

This paper highlights on the error performance improvement of 4 ×4 Extended Alamouti Scheme with implementation of Eigen-Beamforming technique. In a MIMO communication system, the beamforming technique improves the Signal-to-Noise Ratio (SNR) and/or Signal-to-Interference-plus-Noise ratio. So, to get advantage of beamforming technique, 4x4 Extended Alamouti Scheme is implemented with Eigen beamforming technique. This combined technique comprises of channel state information which is fed back to the transmitter side in order to achieve proper error performance as compared to Extended Alamouti Scheme without Beamforming. This proposed scheme provides array gain by increasing the bit-error-rate (BER) performance for different wireless communication channels and M-PSK modulation scheme.
