Embodiment 1
[0086] The control method of the adaptive power carrier communication device provided by the embodiment of the present invention is as follows: figure 1 As shown, as a preferred embodiment, the method for controlling the carrier generator to generate the carrier signal by the main controller provided in the embodiment of the present invention is as follows:
[0087] (1) The target bit width of the phase accumulator is determined by the monitoring device according to preset conditions, the preset conditions including sampling frequency, frequency resolution, maximum frequency deviation and noise ratio.
[0088] (2) Decomposing the phase of the target bit width to obtain the phase of the first bit width and the phase of the second bit width. The sum of the first bit width and the second bit width is equal to the target bit width.
[0089] (3) Obtaining and storing a function value corresponding to the phase of the first bit width and the phase of the second bit width according ...
Embodiment 2
[0098] The control method of the adaptive power carrier communication device provided by the embodiment of the present invention is as follows: figure 1 As shown, as a preferred embodiment, the embodiment of the present invention provides a method for collecting the carrier signal generated in step 1 by the signal monitoring device, and using a signal booster to enhance and amplify the collected carrier signal as follows:
[0099] (1) The mobile terminal obtains the carrier signal strength through the signal strength obtaining device, and compares the carrier signal strength with a preset first signal strength threshold.
[0100] (II) If the carrier signal strength is less than the first signal strength threshold, the mobile terminal sends a request to enhance the carrier signal to the main controller.
[0101] (III) The main controller receives the number of requests to enhance the carrier signal, and compares the number with a preset number threshold. If the number is great...
Embodiment 3
[0106]The control method of the adaptive power carrier communication device provided by the embodiment of the present invention is as follows: figure 1 As shown, as a preferred embodiment, the method for aggregating the enhanced and amplified carrier signals in Step 2 through the carrier aggregation program provided by the embodiment of the present invention is as follows:
[0107] a) Aggregating the low-frequency carrier and the intermediate-frequency carrier by using a duplexer through an aggregation program to form a low-intermediate frequency carrier.
[0108] b) When the terminal is in the single carrier working mode, using a switch to open the port of the low intermediate frequency carrier or the port of the high frequency carrier, so as to control the operation of the low intermediate frequency carrier or the high frequency carrier.
[0109] c) When the terminal is in the multi-carrier operating mode, a corresponding first impedance matching network is set in front of t...
