摘要：Channel-dependentscheduling of transmission of data packets in a wireless system is based onmeasurement and feedback of the channel quality. To alleviate the performance degradationdue tosimultaneousmultipleimperfect channel qualityinformation (CQI), asimpleand efficient packetscheduling(PS)algorithm is developed in downlink LTEsystemfor real time traffic.Afrequency domainchannel predictor based on Kalman filteris first developedtorestore thetrue CQI fromerroneous channelquality feedback.Then, a time domain groupingtechniqueemploying the joint of Proportional Fair(PF)and Modified Largest Weighted Delay First (M-LWDF)algorithmsisused. It wasprovedthis proposalachievesbetter performance in terms of systemthroughputand packet loss ratio by simulation results
