Title
Adaptive Modulation/TDMA/TDD with Convolutionally Coded Type-II Hybrid ARQ for Wireless Communication Systems
Abstract
This paper proposes a time divisionmultiple access/time division duplex (TDMA/TDD)-basedadaptive modulation system (AMS) with aconvolutionally coded Type-II Hybrid automatic repeatrequest (ARQ) protocol to achieve high throughput datatransmission in wireless communication systems. First,this paper discusses the cause of throughputlimitation of the conventional fixed-rate quaternaryphase shift keying (QPSK) with ARQ protocol andsuggests that the effective means to improvethroughput performance are the reduction ofre-transmission probability under bad channelcondition and the increase of transmission bit rate perTDMA/TDD slot under good channel condition. Based onthese strategies, this paper discusses an AMS with aconvolutionally coded type-II hybrid ARQ protocol(type-II hybrid ARQ/AMS) and evaluates itsperformance by computer simulation. The resultsconfirm that the proposed type-II hybrid ARQ/AMS candrastically improve throughput performances comparedto the conventional fixed-rate QPSK with selectiverepeat ARQ protocol (SR-ARQ/QPSK) or a simplecombination of SR-ARQ and AMS (SR-ARQ/AMS) under anychannel conditions, especially under severe channelconditions.
