A Scalable Finite Impulse Response ('SFIR') filter includes a pre-processing section, a post-processing section, and a finite impulse response (“FIR”) Matrix. The FIR Matrix is coupled to the pre-processing section and the post-processing section. The FIR Matrix includes a plurality of filter taps and a plurality of signal paths. Each filter tap of the plurality of filter taps has at least a first input, a second input, a multiplexer coupled to the first input and the second input, and a first flip-flop coupled to an output of the multiplexer. The plurality of signal paths are arranged to allow re-configurable data throughput between the each filter tap of the plurality of filter taps.

Scalable fir filter

A Scalable Finite Impulse Response ('SFIR') filter is disclosed. The SFIR filter includes a pre-processing section, a post-processing section, and a finite impulse response ('FIR') Matrix. The FIR Matrix includes a plurality of filter taps and a plurality of signal paths in signal communication with each filter tap. The plurality of signal paths are arranged to allow re-configurable data throughput between the each filter tap and the pre-processing section and post-processing section are in signal communication with the FIR Matrix.

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.
