Description: 多径信道仿真
有三条固定路径的AWGN多径信道的QPSK系统进行BER性能方针，并与在理想的AWGN信道中同样系统的BER进行比较，为简化模型，作如下假设：
1，信道中有三条路径，包括一条没有衰落的LOS路径和两条具有瑞利衰落的路径。与各路径相应的接收功率以及路径间的延迟差是仿真的参数
2，信道的锐利衰落仅影响发送信号的幅度，不影响瞬时相位。
3，在符号间隔内各多径分量的衰减幅度是常数，并与相邻间隔无关。-Multipath channel simulation There are three fixed path multipath AWGN channel BER performance of QPSK systems approach, and in an ideal AWGN channel BER the same system for comparison, in order to simplify the model, make the following assumptions: 1, There are three channels path, including a no decline LOS path and the two have a Rayleigh fading path. Corresponding with the path to receive power as well as the path delay difference between the simulation parameters of 2, channel sharp decline affects only the magnitude of the transmitted signal, does not affect the instantaneous phase. 3, in the symbol intervals multipath component of the decay rate is constant, and has nothing to do with the next interval.

Description: 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 channel) is a statistical model of radio signal propagation environment. This model assumes that the signal through a wireless channel, its signal amplitude is random, show the "decline" features, and multipath fading signal envelope obeys Rayleigh distribution. As a result, the multipath fading is also called Rayleigh fading. The channel model can be described by the ionosphere and troposphere reflect shortwave channel, as well as a built-up urban environment. Rayleigh fading is only applicable to direct signal from the transmitter to the receiver does not exist, or rice fading channels as channel models should be used.
