Abstract
A multichannel radio receiver may include a radio frequency (RF) subsystem and a digital subsystem. The digital subsystem may be configured to use an analog to digital converter (ADC) to sample input. A channelizer bank within the digital subsystem may include a plurality of channelizers. Each channelizer may receive and translate input into a plurality of channels, the channels having widths that are non-uniform and/or spacing (e.g., spacing center-to-center of adjacent channels) that is not regular. The translation may include re-sampling channels at a rate associated with a modulation scheme. A decoder bank may include a plurality of decoders operating in parallel, each to receive input from a channelizer and each associated with a particular modulation scheme. Thus, the multichannel radio may simultaneously receive on a plurality of channels of arbitrary location, arbitrary spacing and/or arbitrary bandwidth, wherein each channel is associated with one of a plurality of modulation schemes.
