Title:
雑音低減方法及び雑音低減装置
Document Type and Number:
Japanese Patent JP4149734
Kind Code:
B2
Abstract:
Techniques for reducing or eliminating effects of noise on a wireless communication system are provided. In one aspect of the invention, the technique comprises monitoring noise attributable to an interference source that may affect one or more components of the wireless communication system. The interference source being monitored is distant from the wireless communication system to the degree that noise arrives at the wireless communication system within a substantially point source-like angular range. For example, the noise may be attributable to the sun or tropospheric ducting. The technique then comprises initiating one or more operations, as a function of the monitored noise, to reduce or eliminate the effects of the noise attributable to the distant interference source at one or more of the components of the wireless communication system that are determined to be affected by such noise.
