により、送信出力を制御した無線通信装置に関するもの
でおる。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wireless communication device, and more particularly to a wireless communication device in which transmission output is controlled by receiving input electric field strength.
従来の無線通信装置は送信出力を一定にするもの、ある
いは通信が基地局と移動局との場合には基地局の制御に

るなどの問題があった。In the above-mentioned conventional wireless communication device in which the transmission output of the former is kept constant at 1%, if two stations communicating with each other are close to each other, they will output more output than necessary. That is, 87N becomes constant above a certain reception input electric field level, and unnecessary outputs are sent out from each other. On the other hand, when the latter communication is performed between a base station and a mobile station, data is exchanged between the base station and mobile station at the point when the output is switched, and the output changes in stages, so the line Discontinuity is unavoidable, and since the output of the base station is constant, there are problems such as the above-mentioned unnecessary output being sent out.

きる。Therefore, this transmission output power control circuit T functions with this DC voltage as a control signal, and outputs transmission power corresponding to the received input electric field strength to the power amplifier 8. Here, when the received electric field strength is large, the electric field strength of the other station during communication is also large and is more than necessary, so the transmission output power of the own station is suppressed, and conversely, when the received electric field strength is small, the other station's electric field strength is suppressed. control to increase the transmission output of its own station in order to ensure the electric field strength of the station. Then, the output signal of the transmission output power control circuit T is amplified to various levels by a power amplifier 8, and then amplified by a transmission high frequency filter 9. It is transmitted from the antenna 1 via the duplexer 2. As mentioned above, it is controlled to maintain a constant receiving input electric field strength, which means that the receiving input field strength is constant, so the call quality is stable and no more than necessary transmitting power is output, so it is easy to transmit to other systems. The influence of this can be reduced as much as possible, and the current consumption of the device can also be reduced.

Further, the modulator 10 modulates the electric field information of its own station and outputs it to the power amplifier 8 through the drive amplifier 11. After the power amplifier 8 amplifies the transmission information to various levels, the transmission high frequency filter 9. It is transmitted from the antenna 1 via the duplexer 2. on the other hand,
In order to process the information transmitted from the other station, the receiving system adds the output of the demodulator 12 to the transmission output power control circuit T, thereby combining the reception input field strength information or transmission output power information of the other station with the own station's It determines both the received input field strength information and controls the transmission output of its own station. Further, by applying an emergency signal from the emergency signal line 13 to the transmission output power control circuit T, an emergency interrupt is also possible by forcibly increasing the transmission output. In other words, in the communication system using this wireless communication device, the received input electric field strength is constant, and 1) when receiving an electric field forcibly transmitted with high output,
Since the input electric field is 4, it is easy to perform an emergency interrupt. and a certain received input electric field strength,
In other words, the reception is controlled to maintain /, so the call quality is stable, and no more transmission power than necessary is output.
The influence on other systems can be reduced as much as possible, and the current consumption of this device can also be reduced. Furthermore, since the system makes decisions based on both the electric field information of the other station and the electric field information of the own station, the judgments are highly reliable. That is, when the receiving electric field strength of the own station has deteriorated but the received electric field strength of the other station has not deteriorated, as in the case of fading, the transmitting power of the own station is not increased.
