Abstract: In-band full-duplex (IBFD) systems are attracting attention as a key technology for ideally doubling channel capacity for beyond 5G and 6G. First, we propose an analytical model of the effect of N-bit analog-to-digital converter (A/D)… read more here.

DOI: 10.1186/s13634-018-0584-2
Abstract: We consider the problem of distributed representation of signals in sensor networks, where sensors exchange quantized information with their neighbors. The signals of interest are assumed to have a sparse representation with spectral graph dictionaries.… read more here.

DOI: 10.3103/s8756699018060092
Abstract: The effect of the quantization noise of the coefficients of discrete wavelet transform (DWT) filters on the image processing result is analyzed. A multilevel DWT method is proposed for determining the effective bit-width of DWT… read more here.
