Description

消除 MSR接收机 GSM与 LTE干扰的自动增益调控方法及装置 技术领域 本发明涉及无线通信领域,特别涉及消除 MSR( Multi-Standard Radio)接收机 GSM 与 LTE干扰的自动增益调控方法及装置。 背景技术 随着 LTE 技术不断商用, 为了支持从 2G的 GMS网络平滑演进到 LTE, 目前许 多厂家都在研发 Multi-Standard Radio (MSR)基站。 3GPP TS 37.104系列协议规定了 MSR基站射频系统抗干扰能力, 但是对于 MSR基站系统内 GSM和 LTE两者之间互 干扰没有直接定义,而且 MSR技术的商用,必需解决 GSM和 LTE系统内干扰的问题。 在小区内每一时刻 UE激活的个数不同, 并且 UE在整个小区内随时移动, 所以 导致基站接收的到功率也不是一个恒定功率; GSM UE 和 LTE UE两者与 MSR基站 通信是独立的过程, 所以 GSM UE和 LTE UE到达基站功率也不同, 如果基站接收到 的 GSM信号过大, 就会阻塞 LTE信号, 造成 LTE流量的降低; LTE与 GSM帧结构 不同, 导致基站接收机自动增益的调整策略就不能简单按照单制式下的策略来调整, 如果基站按照单制式下的调整策略, 就会造成另一种制定信号的损伤。 发明内容 本发明实施例提供了一种消除 MSR接收机 GSM与 LTE干扰的自动增益调控方 法,用于解决 MSR基站接收机 GSM与 LTE系统内干扰的问题,以保证不影响 GSM 和 LTE信号频谱的变化。 本发明的另一目的是提供一种实现上述方法的装置。 根据本发明第一方面,本发明的一种消除 MSR接收机 GSM与 LTE干扰的自动增 益调控方法包括:在 MSR接收机中设置用于启动增益控制的上门限和下门限;在 LTE OFMD开始时刻, 检测 MSR接收机模数转换器 ADC的 ADC功率; 将检测的 ADC 功率与所述上门限和下门限分别进行比较; 若比较的结果为所述 ADC 功率大于所述 上门限或小于下门限, 则启动 MSR接收机的增益控制功能, 反之, 则不启动 MSR接 收机的增益控制功能。 其中, 所述的启动 MSR接收机的增益控制功能包括: 控制 MSR接收机的射频放 大器 ATT和中频放大器 VGA分别调整其增益。 其中, 所述的控制 MSR接收机的射频放大器 ATT和中频放大器 VGA分别调整 其增益包括: 若所述 ADC功率大于所述上门限, 则控制所述 ATT和所述 VGA分别 降低其增益; 若所述 ADC功率小于所述下门限, 则控制所述 ATT和所述 VGA分别 增加其增益。 其中, 所述的控制 MSR接收机的射频放大器 ATT和中频放大器 VGA分别调整 其增益还包括:若所述 ADC功率大于所述上门限且过大,则通过 GSM与 LTE的调度, 降低 GSM或 LTE发射端的发射功率。 其中, 在启动 MSR接收机的增益控制功能期间, 与其增益控制成反比地在数字 域对 GSM信号进行联动补偿。 其中, 所述的联动补偿发生在激活 GSM时隙之内时。 其中, 在数字域对 GSM信号因联动补偿所造成的延时响应进行响应时延补偿。 根据本发明第二方面,本发明的一种消除 MSR接收机 GSM与 LTE干扰的自动增 益调控装置包括设置在 MSR接收机中的以下部件: 门限设置模块, 设置为设置用于启动增益控制的上门限和下门限;
ADC功率检测器, 设置为在 LTE OFMD开始时刻, 检测 MSR接收机模数转换器 ADC的 ADC功率; 比较模块, 设置为将所检测的 ADC功率与所述上门限和下门限分别进行比较; 增益控制启动模块, 设置为根据比较启动 MSR接收机的增益控制功能, 其中当 比较的结果为所述 ADC功率大于所述上门限或小于下门限时, 启动 MSR接收机的增 益控制功能。 本发明的装置还包括位于 MSR接收机数字域中的增益联动补偿模块, 设置为在 启动 MSR接收机的增益控制功能期间, 与其增益控制成反比地在数字域对 GSM信号 进行增益联动补偿。 此外, 本发明的装置还包括位于 MSR接收数字域的响应时延补偿模块, 设置为 在数字域对 GSM信号联动补偿所造成的延时响应进行响应时延补偿。 相对于现有技术, 本发明的技术效果是, 通过在 LTE OFMD开始时刻检测 MSR 接收机的 ADC功率, 并在该 ADC功率大于上门限或小于下门限时启动增益控制, 可 以把 LTE和 GSM信号功率控制在一定的范围, 避免了 LTE和 GSM信号功率过大或 者过小, 从而解决了现有技术中存在的 GSM信号过大导致的阻塞 LTE信号的问题。 附图说明 图 1是本发明的消除 MSR接收机 GSM与 LTE干扰的自动增益调控方法的示意图; 图 2是实现本发明方法的装置的示意图; 图 3是本发明使用的 MSR接收机的示意图; 图 4是用来说明本发明的增益控制、 增益控制补偿及响应时延补偿对 GSM信号 影响的示意图。 具体实施方式 图 1显示了本发明的一种消除 MSR接收机 GSM与 LTE干扰的自动增益调控方法, 如图 1所示, 该方法包括以下步骤: 在 MSR接收机中设置用于启动增益控制的上门限和下门限; 在 LTE OFMD开始时刻, 检测 MSR接收机模数转换器 ADC的 ADC功率, 由于
LTE OFDM符号存在同步帧头 CP, 所以利用该 CP能保证在用于基带解调的 OFDM 符号内功率恒定。 将检测的 ADC功率与所述上门限和下门限分别进行比较; 若比较的结果为所述 ADC功率大于所述上门限或小于下门限, 贝 lj启动 MSR接收 机的增益控制功能, 反之, 则不启动 MSR接收机的增益控制功能。 关于 LTE OFMD开始时刻,本发明的 MSR接收机利用所接收的 LTE OFMD的同 步帧头 CP进行确定。 上述的启动 MSR接收机的增益控制功能可以包括: 控制 MSR接收机的射频放大 器 ATT和中频放大器 VGA分别调整其增益。 控制 MSR接收机的射频放大器 ATT和 中频放大器 VGA分别调整其增益包括: 若所述 ADC功率大于所述上门限, 则控制所 述 ATT和所述 VGA分别降低其增益; 若所述 ADC功率小于所述下门限, 则控制所 述 ATT和所述 VGA分别增加其增益。 在本发明的上述方法中,控制 MSR接收机的射频放大器 ATT和中频放大器 VGA 分别调整其增益还包括:若所述 ADC功率大于所述上门限且过大,则通过 GSM与 LTE 的调度, 降低 GSM或 LTE发射端的发射功率。可以通过将 ADC功率过大事件上报给 高层, 再由高层通过对 GSM与 LTE调度来实现。 由于 GMS 帧结构和 LTE帧结构不同,根据 LTE OFDM进行增益控制调整,就会 导致 GMS 在每一个 slot内功率不连续,为此本发明在启动 MSR接收机的增益控制功 能期间, 在数字域按照与其增益控制成反比的关系对 GSM信号进行增益联动补偿, 即若增益控制为增益增加时, 则增益联动补偿为增益降低, 反之亦然。 增益联动补偿 应当发生在或落在激活 GSM时隙内时,其他时间不进行补偿。激活 GSM时隙是 MSR 接收机根据 GSM的帧头确定的,也就是说,在检测到 GSM帧头且该帧头与 LTE帧头 重合时, MSR接收机激活 GSM时隙。 由于增益控制本身具有一定的延时, 所以在进行增益联动补偿之后的其 GSM信 号的波形将会变坏, 如图 4所示。 为此, 本发明在数字域对 GSM信号因增益控制补 偿所造成的响应延时进行时延补偿。 图 2显示了本发明的一种消除 MSR接收机 GSM与 LTE干扰的自动增益调控装置, 如图 2所示, 该装置包括设置在 MSR接收机中的以下部件: 门限设置模块, 设置为设置用于启动增益控制的上门限和下门限; ADC功率检测模块, 设置为在 LTE OFMD开始时刻, 检测 MSR接收机模数转换 器 ADC的 ADC功率; 比较模块, 设置为将所检测的 ADC功率与所述上门限和下门限分别进行比较; 增益控制启动模块, 设置为根据比较启动 MSR接收机的增益控制功能, 其中当 比较的结果为所述 ADC功率大于所述上门限或小于下门限时, 启动 MSR接收机的增 益控制功能。 此外, 本发明的装置还可以包括位于 MSR接收机数字域中的增益联动补偿模块, 设置为在启动 MSR接收机的增益控制功能期间, 与其增益控制成反比地在数字域对 GSM信号进行增益联动补偿。 另外, 本发明的装置还可以包括位于 MSR接收数字域的响应延时补偿模块, 设 置为在数字域对 GSM信号因联动补偿所造成的延时响应进行响应时延补偿。 图 3显示了本发明的 MSR接收机的一个实施例, 如图 3所示, 该 MSR接收机包 括用来放大 LTE或 GSM射频信号的低噪放大器 LNA, 射频可变增益放大器 ATT, 将 射频信号转换成中频的变频器 LO, 中频可变增益放大器 VGA、 模数变换器 ADC, 低 频变频器 DDC, GSM滤波器, LTE滤波器, 以及增益联动补偿模块和充当响应延时 补偿模块的数字滤波器。 此外, MSR接收机还包括图中未显示的门限设置模块、 ADC功率检测模块、 比 较模块和增益控制启动模块, 因此这些模块在图 3中由软件实现。 本发明的优点是:
1、 解决了 MSR接收机 GSM与 LTE 信号系统内干扰的问题,
1.1、 在检测到大信号时启动增益控制功能, 可以保证 GSM大信号不影响 LTE小 信号; 或者 LTE大信号不影响 GSM小信号;
1.2、 在检测小信号时候, 启动增益控制功能, 可以保证 GSM 和 LTE信号有足够 大的增益, 从而保证了基带的解调门限;
1.3、 当检测信号过大的时候, 上报高层, 高层通过控制两种制式的发射功率的调 度来解决系统干扰。
2、 支持 LTE 信号符号级解调的同时不会对 GSM解调造成影响。
2.1、 由于无线传输的空间的复杂性, 会导致 LTE—个子帧 ΤΉ内的 14个 OFDM 符号功率不同; 如果按照字帧进行解调 LTE信号, 当其中一个 OFDM出错的时候, 就会造成整个字帧的 CRC校验错误, 由于本发明采用 LTE 信号符号级解调, 从而避 免了此问题的发生。
2.2、 通过采用本发明的增益控制调控方法, 能保证每个 OFDM符号正确的进行 信道估计, 从而提高信号估计的准确性。。 2.3、 由于 GSM速率低, 在基带数字域进行 AGC的联动补偿, 保证 GSM的解调 不受影响。
3、 解决了 GSM动态范围要求。 3.1、 GSM的灵敏度要 -109dBm, 动态范围要求 -15dBm ; 其动态范围将近 100dB, 目前市面上可以买到的 ADC器件 也就 l ibit, ADC的动态范围远小于 GSM的动态范 围;
3.2、 通过引入增益控制策略大大的减小了对 ADC器件的依赖。 尽管上文对本发明进行了详细说明, 但是本发明不限于此, 本技术领域技术人员 可以根据本发明的原理进行各种修改。 因此, 凡按照本发明原理所作的修改, 都应当 理解为落入本发明的保护范围。
