The number of taps and the lag are fixed by the block size chosen for this. It is much larger than the non block lms filters, runs faster, and converges quite a bit more quickly (thus the need for lower gain) because it adapts the taps in blocks. This must be balanced against the ability to make sufficiently discontinuous changes from one block to the next that it introduces serious artifacts.
