A code-aided linear iterative turbo equalizer in a fading channel

A convolutional code-aided linear iterative turbo equalizer (LITE) is presented to be employed in a fading channels in this paper. A method is proposed for exploiting transmittal diversity using parallel independent fading channel together with an iterative equalizing receiver. The structure combines LITE, encoding, decoding interleaving, and de-interleaving. The code-aided LITE employs encoding and interleaver in the transmitter and passes a priori information on the transmitted symbols between decode output in the receiver. The performance of a code-aided LITE is evaluated by means of computer simulation. Compared to the LITE, the proposed equalizer performs in both AWGN and Rayleigh fading channel is given. It shows the proposed convolutional code-aided equalizer functions well in a fading channel.
