FIR cross-talk cancellation
As the processing
network is more involved than a traditional FIR, the number of taps which can
be used is lower. Nevertheless, the perceived performances, on a given DSP
board, are usually better than with a normal FIR
lTodays DSP boards are not powerful enough for convolving long inverse FIR filters
lWarping can be used for concentrating the
computing power in the frequency range
where it is most needed
