Abstract
The details of an improved correlator and efficient method of correlation are disclosed. The last M received signal samples are compared with all shifts of a given M-bit binary codeword. The correlator adds or subtracts each of the signal samples accordingly, as the corresponding shift of the codeword contains a binary '1' or '0' in that position. The total is output for each new signal sample received, with a shift of one position between the signal samples and the codeword.
