Abstract:
1. A method of detecting, by a detection circuit of a receiver, a first signal in a received signal (y) using a pattern (ŝ), the received signal (y) comprising at least one signal group (y (1) , . . . , y (J) ), each signal group comprising a number (K) of signal symbols, the pattern (ŝ) comprising at least one pattern group (ŝ (1) , . . . , ŝ (J) ), each pattern group comprising at least a number (K) of pattern symbols, the method comprising: multiplying, in an accumulator circuit, for each of said at least one signal group (y receiving one or more weight factors (x applying a weight factor (x determining if a signal is detected or not based on said one or more weighted sums (x
