瑞利衰落信道(Rayleigh fading channel)是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后,其信号幅度是随机的,表现为“衰落”特性,并且多径衰落的信号包络服从瑞利分布。由此,这种多径衰落也称为瑞利衰落。 这一信道模型能够描述由电离层和对流层反射的短波信道,以及建筑物密集的城市环境。瑞利衰落只适用于从发射机到接收机不存在直射信号的情况,否则应使用莱斯衰落信道作为信道模型。-Rayleigh fading channel, Rayleigh fading ch

If SDMA is used on the downlink of a multi-user MIMO system,
either long-term or short-term channel state information
has to be available at the base station (BS) to faciliate the joint
precoding of the signals intended for the different users.
