REAL-TIME SEAMLESS WIRELESS MULTIMEDIA COMMUNICATION METHOD USING COGNITIVE COMMUNICATIONS, CAPABLE OF AVOIDING INTERFERENCE

摘要

PURPOSE: A real-time seamless wireless multimedia communication method using cognitive communication is provided to avoid continued interference generated by an electric device and intermittent interference generated by the human body or surrounding environment.;CONSTITUTION: A receiver randomly generates a link identification code(S200). The receiver transmits the link identification code to a transmitter while frequency hopping in a specific frequency group. The receiver sets link frequency for transceiving data using specific frequency group information included in the link identification code(S300). The transmitter and receiver change a channel to the set up link frequency. The transmitter and receiver transmit and receive data(S400).;COPYRIGHT KIPO 2010
