In consideration of the continuous increasing demand of wireless data transmission, ultra-wideband spectrum sensing is crucial to support the cognitive communication in a ultra-wide frequency band. However, it is challenging to design ADCs that fulfill the Nyquist rate requirement for a ultra wide band. Spectrum sensing based on the sub-Nyquist sampling maybe the answer. We propose UWBSS: ultra-wideband...
Generalized robust Chinese remainder theorem has been proposed to reconstruct one positive real number when all the moduli have a common factor and the remainders have errors. In this paper, we consider the generalized robust Chinese remainder theorem to reconstruct multiple numbers when all the moduli have a common factor and all residue sets have errors. We apply the newly proposed theorem to multiple...
This article proposed one kind of new phase difference solution fuzzy algorithm, this method choice base length satisfies certain diverse relations, thus increased the most greatly not fuzzy angle greatly, has solved the direction finding precision and most greatly between not the fuzzy angle contradiction. The simulation result has indicated the theoretical analysis accuracy.
The Chinese remainder theorem (CRT) is an ancient result about simultaneous congruences in number theory, which reconstructs a large integer from its remainders modulo several moduli. It is well known that the CRT has tremendous applications in many fields, such as computing and cryptography, an important one of which could be radar signal processing and radar imaging. However, it is also well-known...
