    Abstract: A radio communication apparatus makes it possible to prevent contents of communication from being intercepted. The radio communication apparatus includes a generation unit configured to generate a first unique word based on operation time information of the radio communication apparatus before communication with a radio communication apparatus is started, and generate, for each radio frame, an ith unique word (i: an integer equal to or greater than two) based on an (i−1)th unique word when the communication is started, and a transmitting unit configured to transmit a first radio frame including the first unique word and an ith radio frame including the ith unique word to the radio communication apparatus.

    Abstract: A radio wave jamming system (1) comprises a plurality of radio transmitters (10) that are adapted to transmit respective jamming signals (11) including substantially the same frequency. The plurality of radio transmitters (10) are further adapted to temporally change at least one of the transmission phases of the jamming signals (11), which are to be transmitted from the plurality of radio transmitters (10), so as to temporally change the phase differences among the jamming signals (11) when the jamming signals (11) transmitted from the plurality of radio transmitters (10) arrive at a particular site (50). Thus, for example, a radio wave jamming system that can be constituted by small-output radio devices can be provided.
