摘要

本文描述了一种具有两个发射天线和两个接收天线的多输入多输出(MIMO)无线系统。我们比较两种不同的方案。第一种模型是基于空时分组编码的Alamouti方案，该方案简化了接收机结构。第二个模型是奇异值分解。该系统的实现是为了研究MIMO如何比SISO或MISO系统提供更好的结果(在BER和PER方面)。

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

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.
