This paper describes a new bandwidth extension algorithm which is targeted at high quality audio communication over IP networks. The algorithm is part of the Huawei/ETRI candidate for the ITU-T super-wideband (SWB) extensions of Rec. G.729.1 and G.718. In the SWB candidate codec, the 7-14 kHz frequency band of speech and audio signals is represented in terms of temporal and spectral envelopes. ...

We focus on coherent Direction Of Arrival (DOA) estimation of wideband sources based spatial sparsity. By development super-resolution algorithms, DOA narrowband has already been addressed gridless sparse algorithms and atomic norm minimization. In this paper, a method is proposed for multiple sources. To do so, we first develop new focusing to map the subband with largest center frequency othe...

This paper presents a method of estimating target location and scattered waveforms, whose accuracies are interdependent. The technique relies on iterative improvements of estimated dominant-frequency waveforms. Description of the algorithm is followed by statistical simulation examples. The performance of the technique is contrasted with conventional methods and statistical bounds in terms of t...

Speech quality models usually estimate the integral quality of the degraded speech files. Such quality values do not inform system developers and telephone service providers on the perceived degradation introduced by the system under study. This paper describes a new intrusive speech quality model, called Diagnostic Instrumental Assessment of Listening quality (DIAL), providing diagnostic infor...

This paper presents a design of Ultra Wideband Low Noise Amplifier (LNA) with Negative Feedback and multisection matching network implementing on Microstrip design technique. The design started with selecting a transistor which is Super-low noise InGaAs HEMT MGF4937AM transistor that support ultra-wideband frequencies. In order to achieve ultra-wideband LNA, two different techniques which imple...
