Abstract
A correlator includes a circuit for serially receiving in phase (I) and quadrature (Q) signal data along parallel I and Q signal channels and converting the data to blocks of n bit parallel I and n bit parallel Q signal data. At least one programmable read only memory (PROM) stores I and Q reference data. The memory receives and stores within each respective parallel I and Q signal channel a current block of n bit parallel I and n bit parallel Q signal data and the immediately previous received blocks of n bit parallel I and n bit parallel Q signal data. A data bus receives the n bit parallel I and Q reference data and the n bit parallel I and Q signal data. The n bit parallel I and Q reference data are correlated with a one bit shifted version of the respective n bit parallel I and Q signal data from an adjacent previous path to produce a correlated I component signal output and a correlated Q component signal output.
