Abstract
A technique for iterative decoding between turbo and Reed Solomon (RS) decoders for improving bit error rate (BER) and packet error rate (PER) in a receiver in a wireless communication system comprises receiving data samples comprising turbo encoded packets and RS code words at the receiver; decoding turbo encoded packets of the received data samples using a turbo decoder; decoding RS code words of the received data samples using a RS decoder; feeding the RS decoded data to turbo decoder to perform a plurality of iterations; and correcting data errors present in the received data samples.
