Abstract
This paper presents a novel architecture using
the decorrelating (DECOR) transformation technique
when applied to an LMS adaptive filter. The DECOR
transform has been evaluated previously, however no
practical evaluation has previously ever been made
of how area and power performance is affected by
the addition of the DECOR transform to an LMS
adaptive filter. Neither has analysis been carried out
to determine any tradeoff in increased area this might
incur against power saved. This paper presents the
first complete architectural VLSI implementation of the
decorrelating transform when applied to an adaptive
