Thanks Brian,
A matched filter is just a FIR filter that does correlation because the coefficients are a specific sequence instead of a frequency response. This is how CDMA works. You "spread" your one bit out over this PN sequence and then use a matched filter to correlate against the expected PN sequence. You can either get a 1 or a -1 depending if you sent a 0 or a 1.
Would any of the FIR filters that already exist in GR be appropriate? I could then perform the cross-correlation on the output of the block.
