A Comparison of Reliability of Wireless Communication Systems for AVHS

In this paper, we analyze the reliability and the bandwidth efficiency of various communication schemes, and investigate the characteristic of short range exclusive communication architecture, which is compatible for AVHS of ITS. Block and convolutional coded BPSK, QPSK with perfect CSI in CDMA were considered. Especially, we can find the probability of symbol error and packet error by use of the charecteristic equation. And we also te access of the reliability and frequency efficiency of communication schemes by use of those.
