Abstract

Orthogonal Frequency Division Multiplexing (OFDM) system became an important material for the current researchers. As like other communication systems, OFDM system needs to employ the channel coding to reduce the Bit Error Rate (BER) such as the concatenated Reed Solomon-Convolution code (RS-CC). To enhance more the BER problem, a Reed Solomon-Recursive Convolution code (RS-RCC) over Additive white Gaussian noise (AWGN) and fading channel has been used in this letter with same complexity of (RS-CC). The simulation results prove that the suggested method for different kinds of constellation mapping of various coding rates gives better BER performance than the old method represented by RS-CC.
