We study two sub-Nyquist sampling schemes for multiband signals known as multicoset sampling and multiple-input, multiple-output (MIMO) sampling. A multiband signal is one whose Fourier transform is supported on a set F ⊆ R consisting of a finite union of intervals. Unlike uniform sampling, multicoset sampling allows perfect reconstruction of a multiband input at sampling rates arbitrarily clos...

We predict multiband vector solitons in nonlinear periodic systems, using photonic lattices as a prime example. The solitons consist of two optical fields arising from different bands of the transmission spectrum, which involve both bound state and radiation mode components.

This paper proposes a hybrid multiband (MB) ultra wideband (UWB) system with direct sequence (DS) spreading. The theoretical error analysis for the DS-MB-UWB multiple access system with Rake receiver in the presence of multipath and narrowband interference is developed. The developed theoretical framework models the multiple access interference (MAI), multipath interference (MI) and narrowband ...

A reconfigurable microwave photonic (MWP) multiband filter with selectable and switchable passbands is proposed and experimentally demonstrated, with a maximum of 12 simultaneous passbands evenly distributed from 0 to 10 GHz. The scheme is based on the generation of tunable optical comb lines using a two-stage Lyot loop filter, such that various filter tap spacings and spectral combinations are...

PURPOSE To develop a saturation recovery myocardial T1 mapping method for the simultaneous multislice acquisition of three slices. METHODS Saturation pulse-prepared heart rate independent inversion recovery (SAPPHIRE) T1 mapping was implemented with simultaneous multislice imaging using FLASH readouts for faster coverage of the myocardium. Controlled aliasing in parallel imaging (CAIPI) was u...

The clock distribution network consumes nearly 70% of the total power consumed by the integrated circuit since this is the only signal which has the highest switching activity. Normally for a multiband clock domain network we develop a multiple PLL to cater the need. This project aim for developing a low power true single phase clock(TSPC) multiband network which will supply for the multi clock...

OBJECTIVE This study examines the tissue differentiation capability of the recently developed high-resolution ultrasonic transmission tomography (HUTT) system in the context of differentiating between benign and malignant tissue types in mastectomy specimens. METHODS Eight mastectomy patients provided breast specimens with benign and malignant lesions. The specimens were scanned by the HUTT s...

A low profile planar antenna for twelve-band operation in the mobile phone is presented. The proposed antenna radiating elements occupy an area equals 17 × 50 mm are mounted on the compact no-ground portion of the system circuit board to achieve a simple low profile structure. In order to overcome the shortcoming of narrow bandwidth for conventional planar printed antenna, a novel bandwidth enh...

On the basis of analyzing the principle of multicarrier DS-CDMA, we propose a novel multiband complex wavelet based multicarrier DS-CDMA system in this paper by using the optimized multiband complex wavelet as multicarrier basis function. The system bit error rate (BER) performance is investigated over Nakagamim fading channel. Without any cyclic prefix (CP), the proposed system can avoid the d...
