This paper investigates the problem of spectrally compatible waveform design for multiple-input multiple-output (MIMO) radar in presence multiple targets and signal-dependent interference. Unlike existing approaches to designing a single target via output signal-to-interference-plus-noise ratio (SINR) maximization, new method is proposed deal with more general problem, i.e., targets, by minimizing energy overlayed space-frequency bands under constraints similarity individual SINR...

Triple-modular redundancy (TMR), which consists of three identical modules and a voting circuit, is common architecture for soft-error tolerance. However, the original TMR suffers from two major drawbacks: large area overhead vulnerability voter. In order to overcome these drawbacks, we propose new complementary dual-modular (CDMR) scheme mitigating effect soft errors. Inspired by Markov random field (MRF) theory, two-stage system implemented in CDMR, including first-stage optimal MRF...

We investigate the interaction of visible supercontinuum light with fiber Bragg gratings that are UV-written in a birefringent air-silica microstructure fiber.

In this letter, we address the multistatic object localization problem when transmitter position and signal propagation speed are not known. By transforming time delay measurement model, first formulate a non-convex weighted least squares problem, which is then relaxed into convex semidefinite programming (SDP) by applying relaxation. It turns out that SDP too loose fails to achieve Cramer-Rao lower bound (CRLB) performance. To propose tighten adding second-order cone constraint reach better...
