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.

A deserializer that deserializes a high data rate bit stream to extract a set of bits contained therein includes a data sampler, a serial-to-parallel converter, a windowing block, and a phase error detection block. The data sampler over samples the high data rate bit stream to produce a serial group of samples corresponding to the set of bits of the high data rate bit stream. The serial-to-parallel converter couples to the data sampler and converts the serial group of samples into a parallel group of samples. The windowing block receives the parallel group of samples and produces output bits corresponding to the set of bits. The phase error detection block couples to the windowing block, detects errors in the alignment of the overlapping sampling windows of the windowing block, and directs the windowing block to adjust the operation. The phase error detection block and the windowing block compensate for bit stream jitter and intersymbol interference.
