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 GHz spectrum.The main architecture of multiple WPANs accessing the HAN is proposed.The medium access control(MAC)-level coordination solution applied in the access point(AP)for the coexistence of different communication protocols within WPAN is discussed.The diagram of the adaptive FRESH filter is described.The anti-interference models of the FRESH filter in the scenario of multiple WPANs accessing the HAN are proposed.The minimum mean square error(MMSE)convergence property of the FRESH filter with the change in the data point number is analyzed.The simulation results indicate that the FRESH filter can effectively extract the signal of interest(SOI)from the interference with the partly overlapped spectrum.Thus, the excellent anti-interference performance of the FRESH filter is validated.Moreover, by both theoretical analysis and simulation, the MMSE convergent property of the FRESH filter is also proven.
