Evolving Turbo Code Interleavers by Genetic Algorithms
Since the appearance in 1993, first approaching the Shannon limit, the Turbo Codes gave a new direction for the channel encoding field, especially since they were adopted for mult...

Blind Turbo Channel Estimation of QAM Signals Exploiting Code Constraints
—We present a blind turbo equalizer for QAM signals that exploits the statistics that a channel code imposes on the transmitted signal. The receiver is an adaptation of previous ...
