The Windows Media Audio (WMA) system uses the waveform coding concepts of subband/transform coding, quantization, and variable length coding to achieve its compression. In addition it models properties of human auditory system to achieve the highest
Abstract-Traditional speech information hiding methods have several disadvantages, for example, constant embedding amplitude, lower speech quality, higher bit error rate. A novel speech information hiding method based on Itakura-Saito measure and ps
The RF3826 is a wideband Power Amplifier designed for CW and pulsed applications such as wireless infrastructure, RADAR, two way radios and general purpose amplification. Using an advanced high power density Gallium Nitride (GaN) semiconductor proce

This paper describes a low power implementation of the
Bluetooth Subband CODEC (SBC) for high-fidelity wireless
audio. The design uses a configurable Weighted Overlap-Add
(WOLA) filterbank coprocessor to implement the analysis and

This paper investigates and solves the problem of frame bound ratio minimization for oversampled perfect reconstruction (PR) filter banks (FBs). For a given analysis PRFB, a finite dimensional convex optimization algorithm is derived to redesign the
Subband beamforming has found many applications in microphone array processing field, due to its advantages over the fullband counterpart. In this paper, the performance of nearfield subband beamformers for arbitrary arrays in the presence of microph
This paper presents a novel blind robust digital image watermarking scheme using nonnegativematrix factorization (NMF) in DWT domain. Firstly, the original image is transformedinto some subband coefficients using discrete wavelet transformation (DWT)
We experimentally investigate multigranularity optical subband switching functionality between two superchannels with slight error vector magnitude penalty. One is 4×39 Gb/s polarization-division-multiplexed (PDM) quadrature phase shift keying discre
