Spectrum Sharing Radar: Coexistence via Xampling
نویسندگان
چکیده
This paper presents a spectrum sharing technology enabling interference-free operation of a surveillance radar and communication transmissions over a common spectrum. A cognitive radio receiver senses the spectrum using low sampling and processing rates. The radar is a cognitive system that employs a Xampling-based receiver and transmits in several narrow bands. Our main contribution is the alliance of two previous ideas, CRo and cognitive radar (CRr), and their adaptation to solve the spectrum sharing problem.

Spectrum sharing is an efficient solution for spectrum shortage. This paper presents mathematical analysis of a typical coexistence scenario between LTE and radar systems in 2.7-2.9 GHz bands. We present the interference analysis of multiple base stations (BSs) and mobile stations (MSs) on the primary radar. The joint distribution of power-controlled and non powercontrolled interference is also...

In this paper, we present our spectrum sharing algorithm between a multi-input multi-output (MIMO) radar and Long Term Evolution (LTE) cellular system with multiple base stations (BS)s. We analyze the performance of MIMO radars in detecting the angle of arrival, propagation delay and Doppler angular frequency by projecting orthogonal waveforms onto the null-space of interference channel matrix....
متن کاملSub-Nyquist Radar: Principles and Prototypes
In the past few years, new approaches to radar signal processing have been introduced which allow the radar to perform signal detection and parameter estimation from much fewer measurements than that required by Nyquist sampling. These systems referred to as sub-Nyquist radars model the received signal as having finite rate of innovation and employ the Xampling framework to obtain low-rate samp...
