摘 要: | 以旋转导向钻井工具的井下短程通讯为研究背景,根据二进制差分编码移相键控(2DPSK)工作原理,利用MATLAB软件实现了2DPSK通讯系统的总体结构及其子模块的仿真设计.通过仿真,研究了影响井下短程通讯误码率的因素,以寻求井下最优工作频率时码元速率及滤波器截止频率的最佳值.仿真结果表明,该系统达到了井下短程通讯的基本要求,在传输信道信噪比较低的情况下具有较好的抗噪性能.2DPSK通讯系统的仿真设计与分析,为下一步全数字井下短程通讯系统的实现提供了依据.

Simulation of the down-hole short-distance communication system based on 2DPSK |
| |
Abstract: | The simulation design of the overall structure and the sub-modules of a 2DPSK communication system are finished according to the principle of binary difference code phase-shift keying(2DPSK) by using MATLAB.The factors of influencing the bit error rate of the short-distance communication system are studied in order to find the optimal values of the code rate and the cut-off frequency of filter at optimal work frequency.The analysis of the simulation result indicates that the system can meet the basic needs of the down-hole short-distance communication,and it has better anti-noise performance in the circumstance of lower signal-to-noise ratio of transmission channel.In this paper,the function simulation and analysis of the 2DPSK communication system provide basis for the implementation of future full-digital down-hole short-distance communication system. |
