基于Matlab的移动通信中多径衰落信道的仿真-Matlab-based mobile communications in the multipath fading channel simulation

移动通信中的抗衰络技术，减少由于信道特性不理想对来的衰落-The anti-contact mobile communication technology, to reduce undesirable channel characteristics due to the decline of the

无线衰落信道 在无线移动信道中，信号从发射天线经过复杂的传播环境到达接收天线，接收信号为各反射、衍射和散射分量以及信道噪声的复合，因而会产生严重的失真。另外，移动信道中由于移动台运动或信道环境的改变会使信道特性随时间随机变化，接收到的信号由于Doppler效应会产生更为严重的失真。 -OFDM has superior performance when transmitting high rate data in wireless fading channel.

在陆地移动通信这种瑞利信道上，比特差错经常是成串发生的。这是由于持续时间较长的深衰落谷点会影响到相继一串的比特。(In the land mobile communication the Rayleigh channel, bit error is often occurred in clusters. This is because the bit deep decline will affect the point of sowing have a longer duration.)
