Abstract

An efficient channel scheduler called the EXP/PF algorithm is proposed to provide real-time as well as non-real time data services demanded by mobile users in an adaptive modulation and coding in time division multiplexing (AMC/TDM) system. It is a composite scheduler of two scheduling schemes. One is the EXP rule applied to real time demanding services to guarantee some delay constraints. The other is based on the PF rule with resource controlling factor applied to non-real time demanding services for maximizing system throughput. Simulation results show that it provides a non-real time user with up to 57.5 % larger throughput than conventional one can.
