Description:
This block is functionally equivalent to a conventional frequency xlating FIR filter, with filter taps given by the kronecker product of sequence1 with sequence2.
This block consists of two filtering steps. First, the received samples are filtered using a frequency xlating filter with frequency offset equal to center_freq and taps equal to sequence2. Second, the output is fed into a S/P converter to generate len(sequence2) parallel substreams, and each substream is filtered with identical filter with taps equal to sequence1. Then all substreams are connected to a P/S converter to generate the output sequence.
Complexity discussion:
Originally the filter taps have length len(sequence1)*len(sequence2).
For the kronecker we have one filter of len(sequence2), followed by a bank of len(sequence2) filters, each of length len(sequence1) operating at a rate 1/len(sequence2), for a total complexity of roughly len(sequence2)+len(sequence1), thus resulting in considerable complexity reduction.
Args:
sequence1: the identical taps of each parallel filter in the filter bank.
sequence2: the taps of the first filter.
samp_rate: the samp_rate of the first freq_xlating_fir filter.
center_freq: the center frequency of the freq_xlating_fir filter.
