Abstract
Techniques are provided for a dynamically reconfigurable two times (2×) oversampled channelizer. A channelizer implementing the techniques according to an embodiment includes a polyphase filter, a two phase reorder circuit, a fast Fourier transform (FFT) circuit, and a two phase merge circuit. The polyphase filter is configured to filter time domain input data to control spectral shaping of frequency bins of the channelizer output. The two phase reorder circuit is configured to split a 2× oversampled data stream into two parallel, critically sampled data streams. The FFT circuit is configured to transform each stream into the frequency domain. The two phase merge circuit is configured to merge the two streams of frequency domain data into a single stream of 2× oversampled frequency domain data for distribution onto frames of frequency bins. Reconfigurable parameters for the channelizer include filter coefficients, number of filter folds, and number of frequency bins.
