Iterative Frequency-domain Int Cancellation for DS

Abstract— The bit error rate (BER) performance of DSCDMA in a frequency-selective fading channel can be significantly improved by the use of frequency-domain equalization (FDE). However, for a small spreading factor SF, the residual inter-chip-inference (ICI) degrades the BER performance. In this paper, we propose an iterative frequency-domain ICI cancellation (FD-ICIC) scheme for DS-CDMA. In t...

Frequency domain processing of ultra-wideband signals

The central challenge of ultra-wideband (UWB) radio is to overcome its intrinsic complexity. This paper argues for the use of high-speed sampling and a front-end FFT as the paradigm of choice for robust performance and low energy consumption in certain ultra-wideband designs. Assuming the need to approach optimal performance, it highlights the complexity advantage of frequency domain (FD) over ...

A robust step-size control algorithm for frequency domain acoustic echo cancellation

The presence of near-end interferences and echo path changes make it essential for an adaptive filter to vary its learning rate according to corresponding conditions. In this paper, a robust step-size control algorithm which is based on the optimization of the square of the bin-wise a posteriori error is proposed. To prevent the adaptive filter from diverging in the presence of interferences, c...

Computationally efficient frequency-domain combination of acoustic echo cancellation and robust adaptive beamforming

For hands-free acoustical human/machine interfaces, e. g. for automatic speech recognition or teleconferencing systems, microphone arrays using robust Generalized Sidelobe Cancellers (GSCs) in conjunction with acoustic echo cancellation (AEC) can be efficiently applied for optimum communication. This contribution devises a new structure for combining AEC and GSC. It reduces the computational co...
