matlab 从入门到精通，比较适合matlab初学者使用！希望对大家有所帮助！(matlab from entry to the master, more suitable for matlab beginners! We want to help!)

his packet is a IS-95 baseband simulation for 1 data channel of 9.6 KBps rate. The simulation is written for static channel and AWGN noise. The packet include: 1) Packet Builder (Viterbi Encoding, Interleaver, PN generation) 2) Modulator (RRC filter) 3) Demodulator (Matched Filter, RAKE receiver) 4) Receiver (HD or SD) (Deinterleaver, Viterbi Decoder). You should run "Simulation.m" function that include all modules.(his packet is a IS-95 baseband simulation f or a data channel rate of 9.6 KBps.

说明：  对一个16元等距线阵，间距为半个波长，空间5个相互独立信源从不 同方向入射，信噪比分别为30、25、20、15、5dB。采用MUSIC方法估 计其空间入射方向(For a 16 element equidistant linear array, the spacing is half a wavelength, and five independent sources are incident from different directions. The SNR is 30, 25, 20, 15 and 5dB respectively. Music method is used to estimate the spatial incident direction)
