Abstract
A modem is configured for demodulating a communication signal associated with a unique code-division multiple access (CDMA) code. The modem includes an adaptive matched filter and a vector correlator. The vector correlator generates filter coefficients for the adaptive matched filter based on signal distortion determined by the vector correlator. The vector correlator has a processing capacity of at least eleven chips whereby the vector correlator compensates for a known phase distortion and for multipath distortion ascertainable within its processing capacity. The adaptive matched filter processes communication signals with the unique CDMA code using coefficients generated by the vector correlator.
