Window Block Control Class
The Window Block is a windowing block for RFNoC that is intended to be used with the FFT block. The block can be configured with coefficients, by which the samples in each input packet are multiplied before begin output. The first sample of the first packet is multiplied by the first first coefficient, the second sample is multiplied by the second coefficient, and so on.
The RFNoC window block supports a configurable number of pairs of input and output ports of sc16 data (16-bit fixed-point complex samples) and a configurable window length and coefficients for each.
