附图概述

图 3为雷达脉冲信号示意图;
图 4为本发明实施例的一种通信系统中抑制脉冲干扰的装置的示意图。
本发明的较佳实施方式 下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是, 在 不冲突的情况下, 本申请中的实施例及实施例中的特征可以相互任意组合。
图 1为本发明实施例的一种通信系统中抑制脉冲干扰的方法的流程图, 如图 1所示, 本实施例的方法包括:
Sl l、 根据信号的功率判断出现脉冲干扰的位置;
首先可以对信号分段, 将信号按照脉冲干扰的持续时间进行分段, 如果 脉冲干扰持续时间不固定, 则以其最短的持续时间为单位, 将信号进行分 段, 然后计算分段信号的段内功率。
选择性地, 可以根据脉冲干扰特征, 在频域对信号进行分段。
将相邻的每两段信号的功率依次进行比较, 如果功率比值大于某一门限 值, 则有干扰存在, 可以将两段中的前段信号位置上置标识 T, 否则, 置标 识' 0'。 根据数组中 Ό'和 'Γ的位置判断出干扰的位置, 门限值可以根据通信系 统中正常信号和脉冲干扰的幅度范围进行设定。
S12、 对该位置上的脉冲干扰的数据段进行抑制处理。
通信系统中的接收机在判断出该位置上有脉冲干扰后, 则将脉冲干扰的 数据段丟弃, 并反馈未收到该数据的指示。
在通常的通信重传机制中, 重传的数据与先前的解析错误的数据进行合 并以降低码率, 提高解调性能, 这对由于噪声或信道衰落引起的解码错误有 较好的解调性能提升。 但发明人发现对于由大幅度脉冲干扰引起的解调错 误, 尤其是脉冲干扰持续时间较长时, 通常的重传机制并不能带来数据合并 增益, 反而会把脉冲干扰引入到重传的数据中, 影响合并后的解调性能。 因 此, 本发明实施例对于脉冲干扰下的接收机行为作了约束: 接收机丟弃被脉 冲干扰的数据段, 这样在有重传机制的通信系统中, 则可以避免被干扰的数 据段参与数据合并而带来性能损失。
下面给出本发明的一个具体实施例。
在规划频谱时, LTE ( Long Term Evolution, 长期演进)无线通信系统可 能会和雷达系统的频带存在部分重叠, 雷达系统以脉冲的形式发射信号, 一 种典型的测距雷达脉冲如图 2所示, 每秒最大 90次的脉冲对, 脉冲对两个脉 冲的间隔为 12us或者 30us左右, 每个脉冲的宽带为 4us左右, 强度是 500W 功率。 当 DME ( Distance Measure Equipment , 距离测量设备 )在 LTE机载接 收频点内的话(5MHz之内 ) , LTE机载台接收功率有 13dBm; 当 DME在 LTE机载接收频点 1MHz之外的话, LTE机载台接收功率为 23dBm, 而 LTE 航线覆盖本身信号最大接收功率仅为 -60dBm。 因此, 当航线的频段和 DME 频段很近的时候, 会有强脉冲干扰, 如图 3所示, 因此, 需要检测出存在脉 冲干扰的子帧, 进行后续的干扰抑制处理。
在该实施例中处理过程如下:
a): 结合实现简便性和干扰抑制策略, 以 LTE系统中的符号长度为单位 将信号进行分段并计算每符号长度的信号功率。
b): 比较相邻的每个符号间的功率, 如果功率比值大于设定的门限值, 则有干扰存在, 将两符号的前符号位置上置标识 T , 否则, 置标识 '0'。 根据 得到的标志位数组, 判断干扰的符号位置。 干扰位置判断方法如下: 找出标 志位数组中每两个相邻的 T (两个 T之间有 Ό', 也认为是相邻的) , 第一个 Τ 开始后到第二个 Τ之间的位置即为干扰的符号位置。 图 3 所示的信号中, 比 较相邻符号功率差后得到的标志位数组为 '1 1 0 0 0 0 0 0 0 0 0 0 0', 数组的前 两位为相邻的两个 Τ, 第一个 Τ开始后到第二个 Τ之间的位置即第 2个符号存 在干扰。
c) : 根据干扰的符号位置, 判断干扰符号所在的子帧是否存在脉冲干 扰, 如存在脉冲干扰, 则将该子帧的干扰数据丟弃并反馈 DTX信息, 且不 维护本次调度的 DCI信息。 这样处理可以保证被干扰的子帧数据不会参与 HARQ合并, 从而降低脉冲干扰的影响。 ( Universal Mobile Telecommunications System, 通用移动通信系统)等。

在一较佳实施例中, 所述第一单元 411通过如下方式将信号进行分段包 括: 将信号按照脉冲干扰的持续时间进行分段, 如果脉冲干扰的持续时间不 固定, 则以最短的持续时间为单位将信号进行分段。
