Abstract : A digital m of n correlation device using signal and reference shaft registers, modulo 2 adders, unique 1-bit D/A converters, and single resistor analog summing provides a very fast correlation product for pulse compression modulations such as phase or frequency shift keying. The compression ratio for the digital m of n correlation device according to the present invention is 168;1 (equal to the number of bits). The device is capable of bit rates in excess of 100 Mbs and is well suited for LSI fabrication.
