步骤S303，若接收到的发射信号的强度低于设定的阈值，则通过调节发射天线的调谐匹配参数，将发射天线的发射信号强度调节至预设值。Step S303: If the strength of the received transmission signal is lower than a set threshold, adjust the transmit signal strength of the transmit antenna to a preset value by adjusting a tuning match parameter of the transmit antenna.
具体的，步骤S303，包括： Specifically, step S303 includes:
若发射信号强度小于预设阈值时，通过切换预设的发射天线的调谐匹配参数值，将发射天线的发射信号强度调节至预设值。If the transmit signal strength is less than the preset threshold, the transmit signal strength of the transmit antenna is adjusted to a preset value by switching the preset tuning parameter value of the transmit antenna.
例如：设置如下不同使用场景的发射天线的调谐匹配参数值：For example: set the tuning matching parameter values of the transmitting antennas of different usage scenarios as follows:
M1：自由空间的发射天线的调谐匹配参数值；M1: tuning matching parameter value of the transmitting antenna of the free space;
M2：右手握移动终端的发射天线的调谐匹配参数值；M2: the tuning matching parameter value of the transmitting antenna of the mobile terminal in the right hand;
M3：左手握移动终端的发射天线的调谐匹配参数值；M3: the tuning matching parameter value of the transmitting antenna of the mobile terminal in the left hand;
M4：双手握移动终端的发射天线的调谐匹配参数值。M4: The tuning matching parameter value of the transmitting antenna of the mobile terminal is held by both hands.
若发射信号强度小于预设阈值时，通过切换预设的发射天线的调谐匹配参数值(M1至M4)，将发射天线的发射信号强度调节至最大值。If the transmitted signal strength is less than the preset threshold, the transmit signal strength of the transmit antenna is adjusted to a maximum value by switching the tuning match parameter values (M1 to M4) of the preset transmit antenna.
在同一匹配下，对于同一频段谐振状态在不同使用场景模式下，发射天线的频偏有一定规律，比如手握相比自由空间状态下会向低频段频偏，根据不同场景发射天线的频偏引起的失配程度不同，天线发射的电磁波能量被吸收的大小不同，通过切换预设的发射天线的调谐匹配参数值，将发射天线的发射信号强度调节至最大值，能够有效节省调谐发射天线的调谐匹配参数值收敛的时间。Under the same matching, for the same frequency band resonance state, the frequency offset of the transmitting antenna has a certain regularity in different usage scene modes. For example, the hand frequency will be shifted to the low frequency band compared with the free space state, and the frequency offset of the transmitting antenna according to different scenarios. The degree of mismatch caused by the difference is different. The electromagnetic wave energy emitted by the antenna is absorbed differently. By switching the tuning matching parameter value of the preset transmitting antenna, the transmitting signal strength of the transmitting antenna is adjusted to the maximum value, which can effectively save the tuning transmitting antenna. Tuning matches the time at which the parameter values converge.
