AB - In this paper, we propose a simply modified Turbo coding structure and investigate its performance in conjunction with Gray coded 16-quadrature amplitude modulation (QAM) over correlated Rayleigh fading channel. Instead of conventional Turbo encoder producing a single parity stream of bits after single operation of a RSC encoder using information bits, the modified Turbo encoder outputs two independent bit parity streams after two times operation of RSC with information bits divided into two streams with bits for each. During iterative decoding at the receiver, the received two independently RSC coded parity streams are independently decoded and apply for this process after constituting these streams to a single stream like the conventional structure. With the proposed structure, we can obtain not only improved decoding performance in moderate/high Doppler spectrum but also compatibility with conventional Turbo code structure.
