Abstract
An array of signals is adapted and dithered by use of a weight signal, a gradient signal with a carrier at a first frequency and an orthogonal sequence signal with a carrier at a second frequency, the dithered signals are then operated on to extract an output signal, a gradient signal, and a weight signal, which gradient and weight signals along with a generated orthogonal sequence signal, are then fed back for use in the dithering process. The carriers at different frequencies provide separability of predetermined components during the operation.
