Abstract


Accurate Error control is a necessary constraint for the design of Celluar 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 transrecevier 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.
