Abstract :
As a powerful coding technique, turbo codes are a prime candidate for improving the reliability of communication over wireless channels, where fading is the main impairment. However, to date, only limited attention has been given to the performance of turbo codes on fading channels, and the influence of multipath fading has been fairly accurately investigated as far as the Rayleigh fading distribution is concerned only. Therefore, it is the purpose of this work to conduct a study of turbo codes performance considering the more general Rice fading case: the study is performed in conjunction with both the fully-interleaved channel and the correlated Rice slow-fading channel
