ABSTRACT:
An improved receiver for modulated bandspread carrier signals is disclosed. The invention includes an antenna for intercepting a plurality of modulated carrier signals bandspread at a first clock rate; a radio frequency section in communication with the antenna for selecting a received signal from the plurality of signals; and an intermediate frequency section in communication with the radio frequency section for converting the received signal to an intermediate frequency signal. The intermediate frequency signal is digitized and multiplied by a pseudo-random code stored in a first memory for demodulation. Successive demodulation products are added, stored and used to provide in-phase (I) and quadrature (Q) signals. Means are provided to for utilizing the I and Q signals to control the rate and the timing of the multiplication of the digitized signal with the pseudo-random code stored in the first memory.
