Error correction scheme for Multi-carrier CDMA with bi-orthogonal modulation

In order to reduce out-of-band emission and PAPR for Multi-carrier (MC) CDMA system, bi-orthogonal modulation is one of the efficient schemes. However the performance of the scheme rapidly degrades if Hadamard code selection errors are occurred at the receiver. We propose and examine a frequency domain error correction scheme for the system employing Reed-Solomon (RS) code. This basic concept is that a Forward Error Correction (FEC) code corrects the code selection errors for all the subcarriers. An efficient decoding method that not only code selection error but the transmitted bit error can correct is also examined.
