An Adaptive ARQ - HARQ method with BCH Codes

In this paper we try to elucidate transitions between individual schemes in proposed method. Our adaptive method combines pure ARQ (Automatic Repeat reQuest) mode in low channel bit error rate and hybrid ARQ method using two different Reed-Solomon codes in middle and high error rate conditions. The scheme is based on the Go-Back-N protocol in every mode. The main goal is to increase number of states in adaptive HARQ methods and be able to achieve maximum throughput for every channel bit error rate. Optimization of scheme system parameters is described in order to maximize the throughput in the whole defined Signal-to-Noise Ratio (SNR) range in selected channel environment. This model is to be used for the estimation of the noise state in the channel and one of method is used, depending of the noise level.
