Abstract :
This paper proposes a pipeline implementation of quadratic adaptive Volterra filters based on NLMS algorithm for high-speed processing and low power consumption. This implementation also gives a superior convergence performance than that of LMS pipeline algorithm under the colored inputs condition. The proposed implementation has zero output latency and reduced critical path compared to the non-pipelined implementation
