Abstract:
A receiver for processing communication signals based in part on relative power of signal samples wherein relative power is calculated as a function of values corresponding to a plurality of signal samples comprising:a buffer for storing at least values r(r) that correspond signal samples Sr that define a set R of samples, where: R is a subset of X consecutively received signal samples S0 through SXâˆ’1 that corresponding to values r(0) through r(Xâˆ’1), and the number of elements of subset R is less than X such that R contains at least two mutually exclusive subsets of consecutive samples {S0 through Si} and {Sj through SXâˆ’1} and R does not include sample Si+1, or Sjâˆ’1; and a processor operatively associated with said buffer for calculating relative sample power based on values r(r) that correspond to signal sample elements Sr of the selected subset R of X consecutively received signal samples and not based on values r(i+1) or r(jâˆ’1) that correspond to signal sample elements Si+1 and Sjâˆ’1, respectively, such that relative power is calculated based on sample series representing at least two diverse time intervals.
