Architectural synthesis of low-power computational engines (hardware accelerators) for a subband-based adaptive ltering algorithm is presented. The full-band least mean square (LMS) adaptive ltering algorithm, widely used in various applications, is confronted by two problems, viz., slow convergence when the input correlation matrix is ill-conditioned, and increased computational complexity for...

As the wireless communication service is widely used and the demand for wireless repeaters is rapidly increasing because of the easiness of extending service areas. But the interference signals may result in the degradation of the network performance. Adaptive filtering has been a general technique to cancel such interference signals in the communication network. Wideband-Code Division Multiple...

Interference or Noise is the major issue in any communication system. It has been used LMS and NLMS adaptive filters to de-noise the noisy signal and compare with the performance of these filters. Adaptive algorithms are the most effective and elementary. This paper investigates the noise cancellation capabilities of the adaptive filters.
