Throughput of nonbinary type-II hybrid ARQ with adaptive modulation
Lijun Zhang, Victor O. K. Li, Zhigang Cao · 2003
Hybrid automatic-repeat-request (ARQ) combines the advantages of ARQ and forward-error-control (FEC), and can achieve good throughput with very low bit error rate (BER). In this paper, nonbinary HARQ is proposed and analyzed in terms of throughput. In nonbinary HARQ, half rate shortened Reed-Solomon (RS) code is used in the FEC subsystem instead of binary BCH codes. Nonbinary HARQ is also applied in a cell with adaptive modulation and the average throughput is obtained.
