Performance Analysis of Type-II Hybrid ARQ Systems

In this paper, an accurate performance analysis is proposed for type-II hybrid ARQ scheme. As opposed to the existing type-II hybrid ARQ analysis work in the literature, the analysis proposed in this paper takes the dependency of the successive decoding attempts into account. The proposed analysis is applicable for type-II hybrid ARQ schemes with known weight spectrum of the error-correcting codes used. The channel models considered include AWGN and Rayleigh fading. Numerical experiments show that the proposed analysis is accurate in capturing the performance of type-II hybrid ARQ systems at mid-to-high SNR region.
