Abstract
A modified least mean squares adaptive filter method and apparatus is disclosed. The filter coefficients used to perform the FIR multiplications in a least mean squares adaptive filter are time dependent upon a time index. Each tap of the FIR section utilizes a coefficient at a different time index. This allows an implementation in hardware that is modular and easy for implementation in VLSI technologies. In addition, an improve multiplier and accumulator is disclosed for use in implementing the improved least squares adaptive filter.
