Abstract :
The general-order multichannel fast transversal filter (FTF) algorithm is a generalization of the multichannel FTF algorithm in which the orders of the input channels can be independently specified. A normalized version of this algorithm is derived and applied to a special case of a two-input-channel, joint-process estimator: one of the input channels is defined as the unit-delayed joint-process signal. The configuration is an equation error form for least-squares pole-zero (ARMA) system identification; it is also used in decision-directed equalization and echo cancellation. A summary of the algorithm is given in proper execution order, with an operations count for each step.<>
