The disclosed systems, structures, and methods are directed to a wireless receiver. The configurations presented herein employ a signal encoder configured to encode a plurality of received analog signals into a single encoded analog composite signal, in accordance with a variable leading bit orthogonal coding scheme, an analog-to-digital converter (ADC) configured to convert the single encoded analog composite signal into a single encoded digital composite signal containing constituent digital signals, a synchronization module configured to provide the variable leading bit orthogonal coding scheme to the signal encoder, and a signal decoder configured to decode the single encoded digital composite signal in accordance with the variable leading bit orthogonal coding scheme, to output a plurality of digital signals containing the desired information content of the received plurality of analog signals.
