Wireless communication system and receiving device

摘要

In a wireless communication system for performing wireless communication using a white space, a receiving station includes an interference suppression processing part which performs processing to reduce interference which is received by the signal transmitted from a transmitting station at a frequency of the white space, a receiving quality estimation part which estimates communication quality of the communication using the frequency of the white space based on the signal processed by the interference suppression processing part, and a receiving quality informing part which transmits to the transmitting station the communication quality information estimated by the receiving quality estimation part.

主权项

1. A wireless communication system including a transmitting station and a receiving station to perform wireless communication mutually, and performing the wireless communication using a white space, wherein:
the receiving station includes: a signal receiving part which receives a signal transmitted from the transmitting station at a first frequency of the white space; an interference suppression part which performs processing to reduce the interference received with the signal received by the signal receiving part; a communication quality estimation part which estimates communication quality of the communication using the first frequency based on the signal processed by the interference suppression part; and a communication quality information transmitting part which transmits to the transmitting station the communication quality information estimated by the communication quality estimation part; and the transmitting station has: a communication quality information receiving part which receives the communication quality information from the receiving station; a frequency allocation processing part which allocates the first frequency based on the communication quality information received by the communication quality information receiving part as a frequency at the time when a control signal is transmitted to the receiving station; and an allocated result transmitting part which transmits to the receiving station the result of allocation by the frequency allocation processing part.
