步骤 S304, 当 B2与 A2的差值大于或等于第二预设值 D时， 输出相应 的控制信号， 控制射频切换模块 6进行信号输出模块 1连接状态切换处理， 以使信号输出模块 1与分集天线模块 3连接；
当 B2与 A2的差值小于第二预设值 D时， 返回执行步骤 S10。
在本实施例中， 应当说明的是， 主天线模块 2的接收信号质量和接收信 号强度越好， 其传输能力越强。 同理， 分集天线模块 3的接收信号质量和接 收信号强度越好， 其传输能力越强。 当信号输出模块 1与主天线模块 2连接， 并经主天线模块 2发射信号时， 若发射信号的发射功率 P1大于第一预设值， 那么该信号发射链路的损耗较大。 为了减小发射信号的损耗， 分析主天线模 块 2和分集天线模块 3传输能力的操作， 具体判断主天线模块 2和分集天线 模块 3的接收信号强度和接收信号质量哪一个最优。 当分集天线模块 3的接 收信号强度和接收信号质量均优于主天线模块 2接收信号强度和接收信号质 量时， 输出相应的控制信号至射频切换模块 6, 使得信号输出模块 1 与传输 能力更优的分集天线模块 3连接， 从而减小了发射信号的损耗， 提高移动通 讯终端的通话质量。 另一方面， 发射链路的损耗减小， 发射信号的发射功率 也相应地减小， 从而能够节约移动通讯终端的用于发射的能量损耗， 延长移 动通讯终端的续航时间。 结合参照图 5 , 图 5为本发明移动通讯终端的信号发射方法再一实施例 的流程示意图。 步骤 S304之后还包括：
步骤 S305 , 经过预设时间段后， 获取当信号输出模块 1产生发射信号并 通过分集天线模块 3进行信号发射时， 发射信号的发射功率 P2;
步骤 S306, 当发射功率 P2小于或等于 P1时， 返回执行获取当信号输出 模块 1产生发射信号并通过分集天线模块 3进行信号发射时， 发射信号的发 射功率 P2的步骤；
步骤 S307 , 当发射功率 P2大于 P1时， 输出相应的控制信号至射频切换 模块 6, 以控制信号输出模块 1与主天线模块 2连接。
在本实施例中， 当射频切换模块 6控制信号输出模块 1与主天线模块 2 连接切换为信号输出模块 1与分集天线模块 3连接后， 获取信号输出模块 1 经分集天线模块 3发射信号的发射功率 P2。 若 P2大于 PI , 则表明分集天线 模块 3发射信号的损耗大于主天线模块 2发射信号的损耗。 输出控制信号至 射频切换模块 6, 以控制信号输出模块 1切换回与主天线模块 2连接的状态。 若 P2小于或等于 P1 , 则表明分集天线模块 3发射信号的损耗小于主天线模 块 2发射信号的损耗。 信号输出模块 1仍可继续通过分集天线模块 3进行发 射信号。 不断获取发射功率， 一旦发射功率 P2大于 P1 , 则切换回主天线模 块 2进行发射信号， 从而能够有效地获取最优的发射链路， 减小移动通讯终 端发射至基站的信号损耗。 执行步骤 S307时， 增大第二预设值 D。
在本实施例中， 信号传输模块 1由与主天线模块 2连接切换至与分集天 线模块 3连接后， 当信号传输模块 1经分集天线模块 3发射信号的发射功率 P2要大于切换前的发射功率 P1时， 则增大第二预设值 D。 在本实施例中， 第二预设值 D增大一。 第二预设值 D作为校验值， 增大第二预设值 D, 能够 减小下一次判断主天线模块 2和分集天线模块 3的传输能力的误差， 从而避 免判断进入死循环， 提高了传输能力判断的准确度。 增大第二预设值 D, 保 证了移动通讯终端的信号能够通过最优的发射链路进行发射，减小信号损耗， 提高移动通讯终端的通话质量。 以上仅为本发明的优选实施例， 并非因此限制本发明的专利范围， 凡是 利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间 接运用在其他相关的技术领域， 均同理包括在本发明的专利保护范围内。 本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成， 所述程序可以存储于计算机可读存储介质中， 如只读 存储器、 磁盘或光盘等。 可选地， 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地， 上述实施例中的各模块 /单元可以釆用 硬件的形式实现， 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。
