That is, the S / N becomes constant above a certain level of the received input electric field, and unnecessary outputs are sent to each other. On the other hand, when the latter communication is performed between the base station and the mobile station, data is exchanged between the base station and the mobile station at the time when the output is switched, and the output changes in stages. However, there is a problem that the above-mentioned unnecessary output is sent because the output of the base station is constant.

First, the received input signal received by the antenna 1 passes through the duplexer 2, is passed through the receiving high frequency filter 3 and the frequency mixer 4, is converted into an intermediate frequency signal, and is supplied to the intermediate frequency amplifier 5. The intermediate frequency amplifier 5 amplifies the intermediate frequency signal and supplies it to the received electric field strength detector 6. The received electric field strength detector 6 detects the level of the amplified intermediate frequency signal and outputs a direct current voltage corresponding to the received electric field input to the transmission output power control circuit 7 in a one-to-one correspondence. Therefore, the transmission output power control circuit 7 functions as a control signal using this DC voltage and outputs the 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 partner 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, In order to secure the electric field strength of, the control is performed so as to increase the transmission output of the own station.

As mentioned above, since it is controlled so as to maintain a certain reception input electric field strength, that is, reception S / N, the call quality is stable and the transmission output is not generated more than necessary. Can be reduced as much as possible, and the current consumption of the device can be reduced.

送出電力は増加させないようになる。Next, the operation of the wireless communication device will be described. First,
The received input signal received by the antenna 1 passes through the duplexer 2, the receiving high frequency filter 3, the frequency mixer 4,
It is converted into an intermediate frequency signal and supplied to the intermediate frequency amplifier 5. The intermediate frequency amplifier 5 amplifies the intermediate frequency signal and supplies it to the received electric field strength detector 6. The reception electric field strength detector 6 detects the level of the amplified intermediate frequency signal and outputs a direct current voltage corresponding to the reception electric field input to the transmission output power control circuit 7 and the modulator 10. The transmission output power control circuit 7 functions as a control signal using this DC voltage and outputs the transmission power corresponding to the received input electric field strength to the power amplifier 8. The modulator 10 also modulates the electric field information of its own station and outputs it to the power amplifier 8 through the drive amplifier 11. Then, the power amplifier 8 amplifies the transmission information to various levels, and then the information is transmitted from the antenna 1 via the transmission high-frequency filter 9 and the duplexer 2. On the other hand, in order to process the information transmitted from the other station, the demodulator in the receiving system
By adding the output of 12 to the transmission output power control circuit 7, both the reception input electric field strength information or the transmission output power information of the partner station and the reception input electric field strength information of the own station are judged to determine the transmission output of the own station. Control. Also, by adding an emergency signal from the emergency signal line 13 to the transmission output power control circuit 7,
If the transmission output is forcibly increased, an emergency interrupt is possible. That is, in the communication system using this wireless communication device, the received input electric field strength is constant, so when the electric field transmitted with a high output is forcibly received, the D / U as the input electric field is superior, so it is easy. Emergency interrupt can be enabled.
Then, a certain reception input electric field strength, that is, reception
Since it is controlled to maintain S / N, the call quality is stable,
Since the transmission output is not generated more than necessary, the influence on other systems can be reduced as much as possible, and the current consumption of this device can be reduced. In addition, since the system makes a judgment based on both the electric field information of the partner station and the electric field information of the own station, the judgment becomes more reliable. That is, as in the case of fading etc., the received electric field strength of the own station deteriorates,
When the reception electric field strength of the partner station is not deteriorated, the transmission power of the own station is not increased.

響も軽減することができるなどの効果がある。As described in detail above, according to the wireless communication device according to the present invention, the transmission output is controlled by the reception input electric field strength, so that the S / N during a call is stable, and the line failure due to the gradual change in the output occurs. Since there is no continuity and unnecessary transmission output can be removed, there is an effect that power consumption can be reduced and the influence on other systems can also be reduced.
