Performance analysis of WL alamouti receivers for real-valued constellations in multiuser context

Several Interference Cancellation (IC) schemes have been developed during this last decade for wireless networks to mitigate the effect of intra-network interferences, when each user is equipped with multiple antennas and employs Space Time Block Code (STBC) at transmission. However, these IC techniques all require multiple antennas at reception, which remains a challenge at the handset level due to cost and size limitations. In this context, a receiver able to perform Single and Multiple Antenna IC (SAIC/MAIC) for users using real-valued constellations (such as ASK constellations) and Alamouti scheme at transmission has been introduced very recently. The purpose of this paper is to highlight its great interest in multiuser context by analyzing its mechanism and deriving its performance in terms of Signal to Interference plus Noise Ratio (SINR) and Symbol Error Rate (SER).
