Abstract(in English) | Recently, multi-code MC CDMA has a lot of attention in wireless multimedia communications because of its high bit rate performance. On the other hand, considering hardware implementation, it requires high power amplifier (HPA) with highly linear characteristics. HPA nonlinearity causes high out-of-band spurious emission and high peak to average power ration (PAPR). In order to solve these problems, employing bi-orthogonal modulation instead of multi-code modulation has been studied. As for the error correction coding of the MC-CDMA with bi-orthogonal modulation, the probability of the erroneous Hadamard code selection at receiver is critical for the BER performance compared to the sign bit error. In this paper, we propose an efficient error correcting scheme for the code selection error employing Reed-Solomon (RS) code. Additionally, an efficient decoding structure that can also correct the uncoded sign bit error using feed back RS decoded codeword is proposed. The basic performance of the proposed scheme was evaluated by both theoretical analysis and computer simulations. |
