Diversity combining is specifically targeted to counteract small scale fading. We will therefore use slow, flat, Rayleigh fading as our model for the signal fluctuation. It must be emphasized that the Rayleigh model is the easiest and most trac

球形解码( Sphere Decoder，SD) 算法能以较低的复杂度实现多输入多输出( Multiple Input Multiple Output，MIMO) 系统的最优检测，是当前受到普遍关注的 MIMO 检测算法。对当前球形解码 的 主 要 研究 成 果 进行 综 述，根 据 搜索策略进行分类，重点分析基于深度优先策略的 VB、CL 和基于宽度优先策略的 K-Best、FSD 算法，并且讨论了几种初始半径的选择方法，最后在准静态平坦瑞利衰落环境下对上述算法进行了性能仿真比较-Sphere

瑞利信道模型建模平坦衰落等，并且加入赖斯信道模型进行改进。模拟了信道的小尺度衰落问题，和Clarke模型进行比对-Rayleigh flat fading channel model, and joined the Rice channel model is improved. Simulation of small scale fading channel, and the Clarke model are compared

Aim: To pass a (a) BPSK signal (b) QPSK signal through a flat-fading Rayleigh Channel and observe SNR versus BER plot of the equalized signal.
