Abstract
The present invention is directed to an improved telecommunication receiver for receiving wireless multi-path communication signals. A novel RAKE receiver and a time diverse integration system for the calculation of the relative power of received signal samples are provided. Preferably, the receiver is embodied in a UE or base station of a CDMA wireless telecommunication system, such as a 3GPP system.
Claims23
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 SX−1 that corresponding to values r(0) through r(X−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 SX−1} and R does not include sample Si+1, or Sj−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(j−1) that correspond to signal sample elements Si+1 and Sj−1, respectively, such that relative power is calculated based on sample series representing at least two diverse time intervals.
