Abstract
A spectrally efficient equalization scheme with multilevel modulation is proposed in this paper for combating intersymbol interference caused by the broadband fixed wireless access (BFWA) channel. The complexity of the existing MMSE equalization schemes increases drastically with the channel memory, which make them impractical to implement when signal transmission rate goes beyond a certain limit. The proposed low complexity scheme enables the system to operate at very high data rate, and its complexity does not increase with data rate, which makes it suitable for high data rate BFWA applications.
