Polynomial cancellation coded orthogonal frequency division multiplexing with overlapping symbol periods (Overlap PCC-OFDM) is a modulation technique that is less sensitive to frequency errors and more robust against multipath distortion than OFDM. A cyclic prefix is no longer needed. However, fading is still a problem and will cause bit errors. Error propagation will occur as decision feedback...
cancellation of the divorce registration
In this paper, we present physical layer and system level techniques that can increase the capacity of a multi-beam high throughput satellite (HTS) communication system. These include advanced predistortion and equalization techniques for the forward link, synchronization and non-linear distortion minimization techniques for the return link waveforms. Interference management techniques such as ...
The cancellation of noise & distortion is the main area of concern in many applications of communications, signal processing and biomedical. The adaptive filters are attractive to work with unpredictable noisy inputs and are capable to work in real-time & non-realtime environments. This work emphasizes on the performance comparison of MATLAB Simulation and DSP Processor implementation of an ada...
The surface Electromyography (sEMG) signal is affected by different sources of noises: current technology is considerably robust to the interferences of the power line or cable motion artifacts, but still there are many limitations in denoising the baseline. In this paper we introduce a new technique, named Baseline Adaptive Denoising Algorithm (BADA), for denoising the sEMG signal by wavelet t...
In many cases hearing impaired persons suffer from hearing loss in both ears, necessitating two hearing apparatuses. In such cases, the applied speech enhancement algorithms should be capable of preserving the, so called, binaural cues. In this paper, a binaural extension of the linearly constrained minimum variance (LCMV) beamformer is proposed. The proposed algorithm, denoted binaural linearl...
In an advanced dialogue scenario it can be required that an Automatic Speech Recognition (ASR) system, working in the car environment, is able to react immediately to a driver’s command, while the car-audio is active or while a synthetic prompt is being reproduced (barge-in). In particular the aim of the work presented in this paper is to cancel the interfering car radio signal, addressing the ...
