Efficient link adaptive transmission scheme with turbo IC receivers
摘要
Abstract
An efficient link adaptation (LA)scheme with turbo interference cancelation (IC)re-ceivers is proposed for the 3 rd generation partnership project long term evolution (3 GPP LTE ) downlink.First,the post signal-to-interference-plus-noise ratio (SINR)and effective signal-to-noise ratio (SNR)for turbo IC receivers are calculated.Secondly,the range of rank indication (RI)and channel quality indication (CQI)are calculated by using traditional the LA scheme.Thirdly,an ef-ficient LA scheme is proposed.This method calculates the feedback parameters only in the defined range of RI and CQI and reduces the number of post SINR and effective SNR calculation.The calcu-lated amount of online throughput prediction is then decreased.The simulation results show that the proposed scheme gets more throughputs compared to the traditional LA scheme and obtains 3 .5 dB gain.Meanwhile,the scheme is satisfied with the QoS (Quality of Service).关键词
