An apparatus and method for mixed signal spread spectrum receiving and spectrum aggregation in a receiver having at least one antenna respectively receiving at least one signal are provided. The method includes modulating the at least one signal received by the receiver with at least one unique orthogonal pseudorandom (PN) code, downconverting the at least one modulated signal into at least one baseband signal, combining the at least baseband signal into an overlaid baseband signal and filtering the overlaid baseband signal, converting the overlaid baseband signal from an analog signal into a digital baseband signal, splitting the digital baseband signal into a plurality of signal paths each having the entirety of the digital baseband signal, applying one of the at least one unique orthogonal PN code to each of the plurality of signal paths, and multiplexing the plurality of signal paths into a combined digital baseband signal.
