①传输的数据随机产生，要求采用频带传输（BPSK调制）；
②扩频码要求采用周期为63（或127）的m序列；
③仿真从基站发送数据到三个不同的用户，各不同用户分别进行数据接收；
④设计三种不同的功率延迟分布，从基站到达三个不同的用户分别经过多径衰落（路径数分别为2，3，4）；
⑤三个用户接收端分别解出各自的数据并与发送前的数据进行差错比较。((1) the transmission data is randomly generated, requiring frequency band transmission (BPSK modulation).

2. The spread spectrum code requires the m sequence of 63 (or 127) cycles.

Simulation sends data from base station to three different users, and different users receive data separately.

Three different power delay distributions are designed, and three different users from base stations reach multipath fading respectively (path number is 2, 3, 4) respectively.

Three users receive their respective data separately and compare them with the data before sending.)
