Channel quality has a great influence on bit error rate (BER) of received signal. The scheme to efficiently ensure four kinds of data services provided by IEEE 802.16 standards is an interesting research issue. In this paper, we propose an adaptive scheduling algorithm cross physical (PHY) layer and MAC layer for IEEE 802.16 BWA system. The Signal to Noise Ratio (SNR) on wireless fading channels determines...
In this paper, we study the performance of a channel-adaptive packet transmission system over fading channels with a finite transmit buffer. This transmission scheme combines the essential features of two popular communication techniques, namely adaptive modulation and coding (AMC) and automatic repeat request. Our joint design takes into consideration the size limitation and the dynamic variation...
