  • Publication number: 20130243134
    Abstract: A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.

  • Patent number: 7720172
    Abstract: A radio communication method for transmitting data to radio stations, wherein propagation parameters to be estimated in a receiving station are controlled, based on the data transmitting, by an array antenna comprising a plurality of antenna elements to perform data transmitting in a transmitting station. This allows channels characterized by the propagation parameters to be shared only by particular radio stations, and signals are superimposed on the propagation parameters, thereby realizing radio access in which a high security is retained.
