Stepping correlation
Stepping correlation a principle of operation of a correlation receiver in channel measurement, where pseudo-random sequences are utilized. The transmitted signal consists of a carrier modulated (typically employing phase-shift keying) by a pseudo-random sequence. The received signal is correlated (multiplied) by an exact replica of the transmitted signal by stepping the chip position of the reference signal with respect to the received signal through all or part of the chip positions. The output of a stepping correlator is a time-scaled version of the autocorrelation function of the pseudo-random sequence, or a part of it. The time-scaling factor depends on the rate with which all the chip positions of interest can be stepped. The rate of producing autocorrelation functions can be made much higher than in sliding correlation. See also sliding correlation.
