Abstract :
Efficient, numerically stable and highly concurrent algorithms for adaptive multichannel least-squares lattice filters are presented. The require O(pm2) orthogonal operations to update the linear prediction and estimation errors as well as all reflection coefficients for a m-channel and p-tap problem. Parallel array architectures for high-speed implementations are discussed
