说明：  file:mblms23.m-performs two by three source separation with multipath multichannel blind equalization with two sources and three sonsors by Russell H.Lambert 1995 Must use multichannel ISI as performance measure (instead of MSE, SIR) because of sign flips，permutations，multipath and arbitrary delays in the inverse filter. With given parameters this matlab program took 92 sacs to run on an SGI (Silicon Graphics) Power Challenge (running on a single CPU).
