An Efficient CDMA System Based on Reed Solomon Code (RS Code)

Abstract

Accurate Error control is a necessary constraint for the design of Cellular Code Division
Multiple Access (CDMA) systems. The Block codes can correct twice as many erasures as
errors; the coded performance can be improved. In this paper, we propose ‘An efficient Error
correcting coding in CDMA systems. The system performance is improved using FEC based
on Walsh code and PN sequence. The power consumption of transreceiver is the requirement
for low power communication systems such as wireless personal area networks, low data rate
networks. The FEC schemes are selected based on its performance. To improve
communication robustness, the correcting capabilities shall be seen to determine the transmit
power. The probability of incorrect Decoding can be significantly improved using RS codes.
