Angle Analysis and Blind Equalization in Wireless Sensor Networks

In this paper, a signal transmission model through wireless sensor network (WSN) is presented. Further transmission from the WSN is considered, and an efficient and effective blind equalization scheme from the receiver site is discussed. Utilizing angle computation of the incident signal at the receiver, a new measurement, angle and normalized error, is derived, which is implemented adaptively to find the best channel path for the blind equalizer to be followed. Computer simulations show as example of estimation of the transmitted signal where the proposed equalizer provides a significant improvement relative to the conventional blind equalizers.
