改进预编码OFDM技术在井下通信中的应用

Application of Improved Precoding OFDM Technology in Underground Communication

针对基于OFDM的低压电力线通信技术会产生频谱零点影响井下通信系统的性能,提出并建立了一种新型井下预编码OFDM通信技术,通过仿真进行对比,所提出的新型预编码OFDM通信技术在井下低压电力线通信中具有可行性。

For low-voltage power line communication based on OFDM technology could produce spectral null that effected the performance of underground communication system,it put forward and established new underground precoding OFDM communication technology. Through simulation comparison,the improved new precoding OFDM communication technology had feasibility in underground low-voltage power line communication.
