Combination of Turbo Code and Multi-Channel Reception in Rayleigh Fading Environment

In mobile radio communications there is an ever-increasing demand for high speed and high quality data transmission. Error correction and multi-channel reception are two promising techniques incorporated in the present-day cellular system to attain high-quality and high-speed communication is a multipath fading environment where the rapid variations of the channel gain degrades the transmission quality and limits the speed. Turbo code is a new coding scheme that has gained a lot of attention recently. Rake reception, antenna diversity reception and retransmission are some of the technologies that exploit the multipath fading nature of the channel. As yet, the combined effect of turbo coding and multi-channel reception has not been analyzed. In this paper, we derive the turbo decoding principle in the case of multi-channel reception.
