A good echo cancellation algorithm should have a fast convergence rate, small steady-state
residual echo, and less implementation cost. The normalized least mean square (NLMS) …

Intersymbol interference (ISI) and cochannel interference (CCI) are two primary sources of
signal impairment in mobile communications. In order to suppress both ISI and CCI, space …

Architectural synthesis of low-power computational engines (hardware accelerators) for a
subband-based adaptive filtering algorithm is presented. The full-band least mean square …

Conventional subband adaptive digital filters (ADFs) using filter banks have shown
degradation in its performance because of the non-ideal nature of analysis filters. For this …

The over-sampling subband ADFs are in high demand because of shortening the
convergence of adaptation algorithms and being able to avoid aliasing. However, the …

A method to simulate a room impulse response using optimum quasi bi-orthogonal (OQB)
filters in an octave filter bank structure is demonstrated. It is further shown that the poly …

Hands-free communication techniques are becoming increasingly important in the world of
modern telephony. The convenience of hands-free links is invaluable in teleconferencing …

Inter-symbol interference (ISI) and co-channel interference (CCI) are two major sources to
signal impairment in mobile communications. To suppress both ISI and CCI, space-time …

In many applications of filter banks, a low‐delay filter bank in which the system delay is small
is desirable. In this paper, two new design methods are proposed for low‐delay perfect …
