Abstract:A turbo coded cooperative orthogonal frequency division multiplexing (OFDM) with multiple-input multiple-output (MIMO) antennas scheme is considered, and its performance over a fast Rayleigh fading channel is evaluated. The turbo coded OFDM incorporates MIMO (2 × 2) Alamouti space-time block code. The interleaver design, and its placement always plays a vital role in the performance of a turbo coded cooperation scheme. Therefore, a code-matched interleaver (CMI) is selected as an optimum choice of interleaver and is placed at the relay node. The performance of the CMI is evaluated in a turbo coded OFDM system over an additive white Gaussian noise (AWGN) channel. Moreover, the performance of the CMI is also evaluated in the turbo coded OFDM system with MIMO antennas over a fast Rayleigh fading channel. The modulation schemes chosen are Binary Phase shift keying (BPSK), Quadrature phase shift keying (QPSK) and 16-Quadrature amplitude modulation (16QAM). Soft-demodulators are employed along with joint iterative soft-input soft-output (SISO) turbo decoder at the destination node. Monte Carlo simulated results reveal that the turbo coded cooperative OFDM system with MIMO antennas scheme incorporates coding gain, diversity gain and cooperation gain successfully over the direct transmission scheme under identical conditions.

“…As in the case of punctured coded cooperative scheme, the puncturing operation takes only one parity bit at a time and discards other parity bit [16]. Therefore, the BER performance of punctured turbo coded cooperative OFDM with MIMO antennas scheme is reduced significantly.…”

“…Recently, there has been an evolution in the ground breaking idea of relay assisted cooperative system called coded-cooperation. The coded-cooperation scheme [9] is a combination of cooperative scheme with existing channel coding like Turbo codes [10], Low Density Parity Check (LDPC) codes [11], Convolution codes [12], Reed-Muller code [13] and Polar codes [14,15]. The basic idea of coded-cooperation is to distribute the channel codes over source and relay terminals, i.e.…”

Abstract. This paper investigates the multiple relay codedcooperation scheme based on asymmetric turbo code (ATC) with multiple receive antennas over Rayleigh block fading channels. An encoding scheme based on ATC is proposed for coded-cooperation, i.e. distributed asymmetric turbo code (DATC). The code matched interleaver (CMI) is selected by a rigorous comparison with a uniform-random interleaver (URI). This optimum choice of interleaver at the relay nodes provides maximum benefit
