(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.
