The disclosed systems, structures, and methods are directed to a receiver architecture. The configurations presented herein employ a structure operative to receive a plurality of wireless analog signals, a signal encoding module configured to encode the plurality of received analog signals into a single encoded analog signal based on a coding scheme, a code compression module operative to compress the code scheme. In addition, a spectrum compression module is configured to under-sample the single encoded analog signal to generate a spectrum-compressed digital signal, a spectrum recovery module operative to recover desired information content of the received analog signals from the spectrum-compressed digital signal and to generate a digital recovery signal, and a signal detection module configured to decode the digital recovery signal based on the coding scheme and to output analog signals replicating the received wireless signals containing the desired information content.
