A New Difference Structure-based Decision Feedback Equalizer
Kong Zheng-min · Dianzi xuebao · 2007
Bit error rate(BER) performance and computational efficiency are two keys which judge a multiuser detector's performance.In DS-CDMA,a new multiuser interference cancellation decision feedback equalizer which has error feedback filter, based on difference structure,is presented.Compared with previous multiuser interference cancellation decision feedback equalizer which has error feedback tilter,the new approach reduces computational efficiency by using difference algorithm,also keeps a good BER performance.
