自适应井下信号补偿器
Self-adaptive downhole signal compensator.
【摘要】 文章介绍了一种自适应补偿器的设计方法 ,主要包括自适应补偿结构和算法 ,以及自适应补偿器的描述及软件实现。其目的是对井下失真信号在地面进行软件补偿和校正 ,以克服电缆、温度等原因造成的信号失真。补偿器实时对滤波系数自动进行调整 ,当补偿器调整达到平衡时 ,其输出信号大约等于失真前的原始发送信号。
【Abstract】 The paper introduces the design method about self adaptive filter, including the self adaptive structure and the algorithm, as well as the realization in software. The self adaptive filter can reshape downhole signals, and the distorted signals are compensated and rectified by software on surface. The self adaptive filter automatically adjusts the filter factors. When the adjustment achives equilibrium, the output signals are almost equal to the raw ones.
