Channel amplitude estimation and interference method and apparatus for vector construction

摘要

To provide a method and apparatus one can determine the amplitude and the presence of channels available plurality of signal paths within the one that was created for one communication system corresponding to an effective symbol length of the present invention relates more. In accordance with the spread spectrum multiple systems [SOLUTION] Abstract The present invention is directed to a method and apparatus for a single efficient for interference vector construction and channel determination. Channel determination is performed using a fast Walsh transform steps plurality of series of first. Result of the first set of fast Walsh transform steps corresponding to a plurality valid communication system, is compared to a threshold of one. The result generated from the first set of fast Walsh transform steps multiple number of steps then passed through a second set of fast Walsh transform steps multiple was performed for the results of the series, the amplitude information is determined by the symbol length associated with the plurality of channels generated. Thus, interference plurality of vectors then obtained for each valid symbol length are combined to form a composite interference vector one. Steps and several other fast Walsh transform several steps may be implemented using software modules or hardware components of a multiple shared.
