卷积码的实现，c比matlab快很多。scr ipt for computing the BER for BPSK modulation in AWGN with Hard and Soft decision Viterbi decoding with traceback-discuss a simple binary convolutional coding scheme at the transmitter and the associated Viterbi (maximum li

该代码实现了IS-95物理层的仿真，发送端加噪后，接收端采用硬裁决，计算BER等。学习意义很大。-IS95 Forward link is realized. The AWGN is added by tranmitter,and then caculated by hard decision by reveiver. It is useful for CDMA2000 learner.
