Title:
RADIO COMMUNICATION DEVICE, SWITCHING METHOD, AND RADIO COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2016052001
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the quality of a transmission signal from deteriorating even under high-speed movement fading.SOLUTION: In a radio communication device 30, a quality detection unit 32 detects the communication quality of each channel. A switching control unit 33 performs switching control to reduce the setting modulation multilevel number of a quality deteriorated channel whose communication quality detected by the quality detection unit 32 has dropped to a prescribed level or below, and the setting modulation multilevel number of at least one of two adjacent channels adjacent to the quality deteriorated channel in the frequency axis direction.SELECTED DRAWING: Figure 3
