We propose a strategy that optimally schedules and allocates users for adaptive modulation and coding based orthogonal frequency multiple access systems (AMC-OFDMA). This strategy aims to maximize the average system throughput as a function of bit error rate (BER) and spectral efficiency by exploiting the user diversity. It sorts the available users of an assigned base station (BS) in queues based...
Beyond third generation (B3G) mobile communication systems may allow users to simultaneously launch multiple multimedia applications with very diverse quality of service (QoS) requirements. In order to achieve resource efficiency, if two applications of the same user have different bit-error-rate (BER) constraints, depending on the multi-user mutiple access technology, the symbols of these two applications...
