摘要： PROBLEM TO BE SOLVED: To realize the control from a wireless transmission reception circuit side to a plurality of controlled systems at an antenna side with a simple constitution in spite of the constitution wherein the wireless transmission reception circuit side and the antenna side are connected via a feeder.
SOLUTION: A diversity switch 3 selects either of first and second antennas 1, 2. A transmission reception switch 5 selects a reception state wherein a wireless transmission reception circuit 7 makes reception via a low noise amplifier 4 and a transmission state wherein the wireless transmission reception circuit 7 gives a transmission signal to the second antenna 2 not via the low noise amplifier 4. Then a first control circuit 8 changes a superimposing state of a DC voltage and a pulse onto the feeder 6 synchronously with a switching timing of the antenna used for the reception and a switching timing of the transmission reception and a second control circuit 9 switches the diversity switch 3 and the transmission reception switch 5 on the basis of the change in the superimposing state.

摘要： PROBLEM TO BE SOLVED: To enable stable reception by transmitting/receiving radio signals in cooperation with other radio communication apparatus.
SOLUTION: This radio communication apparatus is provided with an antenna array 2 having a plurality of first antennas 1, a phase shift circuit 3, a reception circuit 4, a control circuit 5, a second antenna 6 and radio device 7 for other apparatus. The stable reception is enabled for the reason that a phase and an amplitude of the antenna array 2 are set by using control signals in other radio communication apparatus since the control signal of the antenna array 2 is transmitted to other radio communication apparatus via the second antenna 6 and on the contrary, the control signal of the antenna array 2 in other radio communication apparatus is received via the second antenna 6. In addition, if representative radio communication apparatus is determined, a radio communication apparatus except it can control the antenna array 2 by using a control signal from the representative radio communication apparatus, thus, processing of individual radio communication apparatus is simplified.

摘要： PROBLEM TO BE SOLVED: To provide a wireless communication system which is excellent in transmission efficiency and power efficiency.
SOLUTION: The wireless communication system includes a wireless base station 10 provided in a communication service area 10 and a plurality of wireless terminals 20 for communicating with the base station 10 via radio channels. Representative one of the wireless terminal stations receives a transmission frame from the base station and transmits the received frame to the respective terminals belonging to the terminal group. Consequently, transmission power of the base station can be reduced, and a large quantity of data such as a moving image or still image can be easily transmitted from the base station to the terminal group. Since the representative terminal can be dynamically changed, one of the terminals having a good wave reception state can be allocated as representative one, stable and reliable communication can be established.
