A comparison between Alamouti and SVD scheme for OFDM based WLAN system

Abstract

In this paper, we describe a multiple-input-multiple-output (MIMO) wireless system with two transmit and two receive antennas. We compare two different schemes. The first model is based on the space-time block coding known as Alamouti scheme, that simplifies the receiver structure. The second model is singular value decomposition. The proposed system has been implemented in order to study how MIMO provides much better results (in terms of BER and PER) than SISO or MISO systems.
