Abstract :
The performance of turbo hybrid-ARQ (HARQ) Type-I, Type-II and Type-III schemes are examined for wideband communications based on an orthogonal frequency division multiplexing (OFDM) system. In addition, various non-linear clustering strategies for minimizing the effects of peak-to-average power (PAP) ratio are compared and examined based on their throughput performance.
