A novel wavelet image coding algorithm based on non-uniform scalar quantization is proposed. This algorithm adopts longer step to quantize the wavelet coefficients in the lowest frequency subband and uses shorter step for other ones. According as the results of the experiment we design a coding ...
In this paper, we apply uniform scalar quantization to the measurements of the speech signal and quantitatively show that how adaptive quantization affects the reconstruction quality compared with the nonadaptive quantization. In addition, we find that the TBD matrix is more robust to the quantization...
system, existing coding solutions which suit for the CSV system are: 1) JPEG [20] based solution MJPEG-differential pulse code modulation (MJPEG-DPCM) [21], 2) uniform scalar quantization (USQ) based solution USQ-DPCM [22], 3) H.264/AVC Intra codec [23], and 4) HEVC Intra codec [...

so its energy spectrum interval is no longer uniform. This allows specific energy levels to be controlled, and the two lowest energy levels can define two quantum states for subsequent calculations. For more complex situations, such as two Josephson junctions connected in parallel to form a quantum...
Each frame is first transformed with a wavelet transform and the resulting frequency bands are quantized with a multiple description scalar quantizer. Two balanced descriptions of the video input are thus generated. The quantization indexes of the WZ frames are coded with an low-density parity-check...

1, consider a mmWave massive MIMO system with uniform linear arrays (ULAs) at the transmitter and receiver. The N-antenna transmitter transmits a training sequence of length T to the M-antenna receiver. Therefore, the received signal \(\mathbf {Y}=[\mathbf {y}[1]\quad \mathbf {y}[2]...
