Abstract
A variable length code often causes loss of synchronization due to bit error in wireless transmission, so that burst errors occur in the received codewords. In this paper, we proposed a wireless transmission technique of variable length code utilizing M-ary/SSMA. Since the information represented by a variable length code is transmitted as the combination of some spreading codes in the proposed system, the synchronization of the codewords is maintained. Besides, this system does not require many spreading codes per user. This paper evaluates the performance of the proposed system over a Rayleigh fading channel.
