Abstract: A system for communicating radio-frequency (RF) signals includes a receiver subsystem that employs a phased antenna array, and signal spreading of the respective responses of the elements of the phased antenna array. The codes used for spreading are unique to each antenna element. The spread signals are combined and analog-to-digital conversion (ADC) is applied to the combined spread signal. The signals to be spread may be grouped according to a signal characteristic such as signal polarization or whether the signal is an in-phase or quadrature signal. A respective signal combiner and a respective ADC may be used for each group. The communication system may include a transmission subsystem that employs signal de-spreading that is unique for each antennal element.
