摘要： Disclosed is radar wave detection and DFS (dynamic frequency selection) with high efficiency while considering, for instance, the power consumption of each communication station within an autonomous distributed network. At least one communication station runs in an interference avoidance operation mode, operates a radar wave detection section, and fulfills the obligation to issue instructions for radar wave detection and DFS for an approximately predetermined period of time. After the lapse of the approximately predetermined period of time, another communication station switches to the interference avoidance operation mode and assumes the obligation to issue instructions for radar wave detection and DFS. In other words, two or more communication stations sequentially run in the interference avoidance operation mode in a time sharing manner. Therefore, the average power consumption of the communication stations decreases.

摘要： A monoconical antenna comprises: a substantially conical concavity formed in one end face of a dielectric; a radiation electrode provided on the surface of the concavity; and a ground conductor provided in proximity to and substantially in parallel with the other end face opposite the one end face of the dielectric. The monoconical antenna is so constituted that electrical signals are fed to between the near vertex region of the radiation electrode and the region of the ground conductor. The half-cone angle α of the substantially conical concavity formed in the one end face of the dielectric is determined by a predetermined rule corresponding to relative dielectric constant ∈r. Thus, the quality of wideband characteristics inherent in the monoconical antenna can be sufficiently maintained, and further size reduction can be accomplished by dielectric loading.

摘要： A scrambling initial value is shared without deteriorating transmission efficiency. On the transmission side, a scrambling initial value is created based on a part of a physical layer header not scrambled, a transmission signal sequence scrambled is created by calculating an exclusive-OR operation between a scrambled sequence generated from the scrambling initial value and a transmission data sequence, and is transmitted. On the reception side, the same descrambling initial value as the scrambling initial value is created based on a part of a physical header of a reception frame, and a reception data sequence is descrambled by calculating an exclusive-OR operation between a descrambled sequence generated from this descrambling initial value and a reception signal sequence scrambled.

摘要： Disclosed is a wideband antenna having a reference conductor and radiation conductor, which are disposed so as to face one another. A substance whose relative permeability is in a range of about 1 though 8 in an operational radio frequency is interposed between the portions of the reference conductor and radiation conductor that face one another. A feed is operatively coupled to the radiation conductor and provides a radio frequency transmission signal thereto. The feed has a tapered shape, which progressively widens as the feed approaches the radiation conductor.

摘要： Under a multi-cell radio communication environment where connection between cells or TDMA frame synchronization is not established, a mobile station carries out an adjacent cell search under low power consumption. Adjacent cell information acquired through search by the mobile station is managed centered on a base station and may be provided by the base station as adjacent cell information, when the mobile station carries out the adjacent cell search. The adjacent cell information includes, for example, a TDMA frame offset between cells so that the mobile station receives a broadcast channel of the adjacent cell at appropriate timing based on the adjacent cell information and therefore does not need to perform unnecessary reception operation in the event of a handoff.

摘要： Disclosed is a wideband antenna with a lowered standing wave ratio. The wideband antenna interposes a substance whose conductivity is about 0.1 through 10.0 as an interposition between a reference conductor and a radiation conductor; and thereby, the antenna reduces reflections of signals, and achieves a wider bandwidth as well as a sufficient gain with a lowered standing wave ratio. Also, the invention realizes a thin-type wideband antenna with a wider bandwidth and a sufficient gain, by interposing a magnetic substance whose relative permeability is more than 1 through about 8 as the interposition between the reference conductor and the radiation conductor.

摘要： A broadband antenna apparatus includes a conducting ground plate, on which a three-dimensional member rests. A radiating conductor is stuck or printed on the three-dimensional member in such a manner that at least part of the radiating conductor is opposite to at least part of the ground plate. A wavelength shortening effect is achieved by the interposition of the three-dimensional member between the opposite parts of ground plate 1 and radiating conductor. This effect makes the broadband antenna apparatus smaller and lower in structure.
