With more degrees of freedom in MSAR, space-time adaptive processing (STAP) based on the inverse of the interference covariance matrix has been widely applied to …
Narrow-band interference suppression in direct sequence spread …
Witryna22 kwi 2015 · Abstract: The use of active narrow-band interference (NBI) suppression in direct-sequence spread-spectrum (DS-SS) communications has been extensively studied. In this paper, we address the problem of optimum coding-spreading tradeoff for NBI suppression. Narrowband signals are signals that occupy a narrow range of frequencies or that have a small fractional bandwidth. In the audio spectrum, narrowband sounds are sounds that occupy a narrow range of frequencies. In telephony, narrowband is usually considered to cover frequencies 300–3400 Hz, i.e. the voiceband. In radio communications, a narrowband channel is a channel in which the bandwidth of the messa… tradingpost kttn.com
Narrow-Band Interference Mitigation for SAR Using Independent …
Witryna31 maj 2012 · Signals come in two flavors, broadband (BB) and narrowband (NB), and, as the name implies, their spectral occupancy is significantly different. Theoretically a … Witryna1 mar 2013 · A narrow-band interference model specifically for an Orthogonal Frequency Division Multiplexing (OFDM) communication system operating over a power-line was described in [12]. We assume an energy ... Witryna21 lis 2013 · The mitigation of narrow-band interference (NBI) is an appealing topic in the synthetic aperture radar (SAR) community. It is an underdetermined single-channel separation problem. This paper proposes a method for NBI mitigation using the independent subspace analysis. First, each single pulse is transformed onto a … the salt and the sea regulus
