Title:
REDUCED COMPLEXITY SLIDING WINDOW BASED EQUALIZER
Document Type and Number:
WIPO Patent Application WO2005004338
Kind Code:
A3
Abstract:
The present invention has many aspects. One aspect of the invention is to perform equalization using a sliding window approach. A second aspect reuses information derived for each window for use by a subsequent window. A third aspect utilizes a discrete Fourier transform based approach for the equalization. A fourth aspect relates to handling oversampling of the received signals and channel responses. A fifth aspect relates to handling multiple reception antennas. A sixth embodiment relates to handling both oversampling and multiple reception antennas.
