INTERFERENCE SIGNAL AVOIDING DEVICE OF A FREQUENCY HOPPING SPREAD SYSTEM AND METHOD THEREOF

摘要

An interference signal avoiding device of a frequency hopping spread system and a method thereof are disclosed. A method of transmitting/receiving an interference signal avoiding signal according to the present invention includes: determining a frequency hopping channel set and a parameter of an interference signal detector in consideration of characteristics of an interference signal; detecting whether there is an interference signal with respect to frequency hopping candidate channels that are to be used for the next frequency hopping by using the determined interference signal detector; transmitting a signal through a channel that is determined by the interference signal detector that there is no interference signal among the frequency hopping candidate channels; searching a channel through which the signal is transmitted from the frequency hopping candidate channels in order to receive the transmitted signal; and performing a transmission power control by using a signal-to-noise ratio of channels having no interference signal during the searching of the channel through which the signal is transmitted from the frequency hopping candidate channels.
