Abstract
Trellis-coded modulation (TCM) has been shown as an attractive coding scheme for broadband wireless networks due to its bandwidth efficiency. Various hybrid automatic repeat request (ARQ) schemes using TCM as underlying forward error control have been proposed in the literature. In this paper, we study the performance of the hybrid ARQ with concatenated two-state TCM (CT-TCM) over Rayleigh fading channels. The throughput of the CT-TCM hybrid ARQ (CT-TCM-HARQ) scheme over a quasi-static Rayleigh fading channel is evaluated by both analysis and simulation. Besides, the performance of the CT-TCM-HARQ over fully interleaved Rayleigh fading channels is evaluated by simulation and compared with other existing TCM-based hybrid ARQ schemes. The numerical results demonstrate that the CT-TCM-HARQ achieves improved coding gain and throughput. © 2007 IEEE.
