Andrea Goldsmith: There's not enough spectrum to assign every phone in the world its own dedicated channel so we have to reuse the channels and that causes interference between users.

安德里亚·戈德史密斯：由于频谱资源有限，我们很难让每个用户享有特定的频段，只能不断地将它们回收利用，导致用户之间出现通信干扰。

Simulation shows co-channel interference and maximum multi-path delay spread have significant impact on the BER performance and PDMRC gives the best performance in most common environment.

仿真表明同信道干扰与最大多径延迟扩展对系统性能影响很大，在通常情况下采用PDMRC具有最好的性能。
