摘要: An environment is considered with many low complexity wireless mobile stations communicating to higher stationary cluster heads. The heads can determine the rough position of using geo-regioning. are not able perform a channel estimation due reasons. We present two approaches utilize regional knowledge available at head for improvement data detection performance station. First, by feeding back average power delay profile from station, station adapt filter according this information. Second, side covariance matrix impulses response vectors used precoding optimization. Based on impulse responses measured in realistic both evaluated. Performance gains 1 3 dB compared energy be obtained.
