Abstract

The authors propose a block adaptive algorithm for estimating the impulse response of discrete-time systems and discuss some of its properties. This algorithm, in which the performance measure is the block mean square error (BMSE), consists of block processing and orthogonal projection arithmetic and updates the adaptive filter´s coefficients once for each block of data. That is, the algorithm is based on orthogonal projection to the subspace spanned by input vectors corresponding to the block index. Some fundamental theorems are derived with respect to this algorithm, and they are substantiated by computer simulations
