Abstract
System and method for efficient wideband code division multiplexing in subband domain include: aggregating L analog signals received from L antenna elements into a single aggregated signal, by using code division multiplexing with L code words, where L is an integer greater than 1; converting the single aggregated analog signal to a single aggregated digital signal, by a single analog-to-digital converter (ADC); channelizing the single aggregated digital signal into N subbands, where N is an integer greater than 1; performing circular convolutions of the N subbands with the L code words to demultiplex the channelized signal into L elements per subband; and routing each subband signal of the L elements to N beamforming circuits for performing beamforming on each of the N subbands.
