Campera-ES Polyphase Filter Bank Channelizer

The polyphase filter must implement a Weigth-Overlap-Add (WOLA) operation on a serial data stream, s(i), multiplying segments of the stream by a filter function, f(i-i0), and then adding together individual frames of the result.

Input samples are presented in frames of nin consecutive samples, with the first sample marked by a sop (start of packet) pulse.

Due to clock speed limitations, samples are usually time multiplexed, i.e. <tmf> consecutive samples are presented together at each clock cycle. The same number of consecutive filtered samples are produced at the output.

The number of channels and the super sample rate factors ( the number of samples presented for each clock cycles) are limited only by the FPGA resources
