- W2372514892 abstract "An adaptive sorted K-best detector(ASK-best)based on estimation of coherence bandwidth is proposed for IEEE 802.11n system.The valid subcarriers are divided into several sub-bands according to coherence bandwidth estimated by Pearson Correlation Coefficient,and the corresponding valid subcarriers in each sub-band are processed by the identical sorted K-best detector.It is proved that the proposed algorithm can provide system performance close to all sorted K-best imposing on each subcarrier.Meanwhile the times of sort can be adaptive according to estimation of coherence bandwidth.In the configuration of 20 MHz bandwidth(56 valid subcarriers)and 4×4 multiple input multiple output(MIMO),compared to 56 times of sort in all sorted K-best,while ASK-best provides the performance close to all sorted K-best,the times of sort are one in flat channel fading of TGn channel A,and about 8 in multipath channel fading of TGn channel C." @default.
