Anti-interference performance analysis of frequency-shift filter in scenario of multiple WPANs accessing HAN
摘要
Abstract
In the scenario of multiple wireless personal area networks (WPANs)accessing the home area network (HAN), the frequency-shift (FRESH)filter based on the cyclostationary theory is applied for the anti-interference at the 2.4 GHzspectrum. The main architecture of multiple WPANs accessingthe HAN is proposed. The medium access control( MAC) -levelcoordination solution applied in the access point(AP) for thecoexistence of different communication protocols within WPANis discussed. The diagram of the adaptive FRESH filter isdescribed. The anti-interference models of the FRESH filter in thescenario of multiple WPANs accessing the HAN are proposed.The minimum mean square error (MMSE)convergence propertyof the FRESH filter with the change in the data point number isanalyzed. The simulation results indicate that the FRESH filtercan effectively extract the signal of interest (SOI) from theinterference with the partly overlapped spectrum. Thus, theexcellent anti-interference performance of the FRESH filter isvalidated. Moreover, by both theoretical analysis and simulation,the MMSE convergent property of the FRESH filter is alsoproven.关键词
