Abstract

We investigate the performance of a new method for implementing high rate turbo codes over complex fading channels with unknown states. The proposed system features the serial concatenation of an outer punctured turbo code and an inner accumulator separated by a nonuniform interleaver. Per-survivor based a posteriori probability (APP) demodulation and turbo processing are applied to achieve iterative channel estimation and decoding under unknown channel states.
