High Sample Rate Architectures For Block Adaptive Filters
- …In this paper we propose a variety of architectures for implementing block adaptive filters in the time-domain. These filters are based on a block implementation of the least mean squares (BLMS) algorithm. First, we present an architecture which directly maps the BLMS algorithm into an array of proc…
