Impulsive interference
Witryna10 kwi 2012 · The impulsive nature of this interference provides an opportunity to reduce its power by nonlinear filtering, improving the quality of the receiver … WitrynaThe proper bandwidth to use in an FM system depends on the application. With a large deviation, noise will be better suppressed (as will other interference), but care must be taken to ensure that impulse noise peaks do not become excessive. On the other hand, the wideband system will occupy up to 15 times the bandwidth of the narrowband …

WitrynaAbstract: This paper presents a new subband adaptive filter (SAF) algorithm for system identification scenario under impulsive interference, named generalized continuous mixed p-norm SAF (GCMPN-SAF) algorithm. The proposed algorithm uses a GCMPN cost function to combat the impulsive interference. WitrynaImpulsive interference is a variety of naturally occurring and man-made phenomena exhibit impulsive behavior. A sentence that summarizes the chaotic nature of impulsive interference is “no two impulsive events are the same”. There are many potential sources of impulsive interference [12]: 1500 1510 1520 1530 1540 1550 1560 1570 …
Witryna1 gru 2013 · A remarkable nature of impulsive interference is that its density function in the tail is heavier than that of Gaussian density [ 6, 7 ]. In recent two decades, there … Witryna21 lis 2014 · This property makes differentiation of interference impulses from OFDM signal peaks a challenging task. Correspondingly, a poorly chosen threshold may impair the OFDM signal significantly. This...
Witryna7 lip 2024 · Our proposed AP-WMLMS algorithm is one robust method for adaptive filtering against impulsive noise. It can suppress the impact of large outliers. Compared with existing LMS algorithms such as WMLMS, our method also takes coloured input signals into consideration. Witryna15 lut 2015 · In particular, impulsive interference that is characterized by a frequent occurrence of outliers (i.e., relatively high-amplitude, short-duration events) can be effectively mitigated by the nonlinear differential limiters (NDLs) described in [1-4] and in Section 4 of this paper.An NDL can be configured to behave linearly when the input …
WitrynaIndex Terms—Narrow-band interference, noise model, Power-line communications, OFDM I. INTRODUCTION It is widely accepted that the power line communications channel is characterised by three main noise types namely, coloured background, impulse and narrow-band interference (NBI). Of these three noise types, the narrow …
WitrynaThe model for narrow-band impulsive interference (Class A noise, a subset of the overall model) is next specifically applied to an important class of coherent signal detection problems. Algorithms for error probabilities in optimum detection are then obtained, along with performance bounds, for the same error probabilities. data collection methods in cyber forensicsWitryna1 godzinę temu · The Prime Minister’s chief of staff, testifying before a House committee on foreign interference, offered little insight into when Trudeau was first apprised of … bitlord usenet free downloadWitryna11 paź 2024 · The HSF and IHSF algorithms can attain superior steady-state performance and stronger robustness in impulsive interference than several … data collection methods geography fieldworkWitrynaWhat is impulsive interference?
