  • Abstract
    A class of turbo-like codes with a crossover component, termed crossover product accumulate (CPA) codes is proposed. This structure is a serial concatenation of a crossover parallel concatenated code and an accumulator through an interleaver. A detailed iterative decoding scheme for CPA codes is described. Simulations show that different crossover depth makes CPA codes have different convergence in bit error rate (BER) performance, and a proper crossover structure produces faster convergence.
