Abstract :
This paper is concerned with a new method to enhance the bandwidth efficiency of an MC-CDMA system by using a residue number based representation for information symbols. The residues are mapped into a set of orthogonal sequences and are transmitted in parallel. A multicarrier modulation scheme is used for both transmission and reception of residue channels. Appropriate error correction methods are employed for enhancing the performance of the system. The paper discusses the simulation results and compares the performances of RNS based MC-CDMA against MC-CDMA for identical channel conditions
