Abstract
A system which receives a pseudonoise sequence signal quantizes the signal during a fixed interval of time and passes the quantized signal to a plurality of correlation channels. Each of the correlation channels rotates the incoming phase modulation at a different fixed rate to cancel out a corresponding component of offset frequency. The outputs of the correlation channels are examined to determine whether acceptable correlation has been attained and, if so, which channel provides the best frequency compensation.
