- 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.
- 在多个无线个域网(wireless personal area network, WPAN)接入家域网(home area network, HAN)场景中, 应用基于循环平稳理论的频移滤波器实现2.4 GHz频段的抗干扰.描述了多个无线个域网接入家域网的总体结构, 讨论了应用于接入点的媒体访问控制(medium access control, MAC)级协作解决方案以保证多个无线通信协议共存于一个无线个域网内, 给出了自适应频移滤波器的框图, 提出了在多个无线个域网接入家域网场景中频移滤波器的抗干扰模型, 分析了频移滤波器最小均方误差随数据积累点数变化的收敛性能.仿真结果表明应用频移滤波器能够从谱重叠干扰中有效地提取有用信号, 从而论证了频移滤波器优良的抗干扰性能.此外, 仿真还论证了由理论分析得出的频移滤波器最小均方误差的收敛特性.
