摘要
SBM(序列平衡调制)以简单的实现方式,通过提取脉冲对的相位差来实现译码和测距,实现数据传输的同时达到测距的目的。对 SBM 的误码性能和测距性能进行分析,采用矢量相位比较技术提高测距精度,并进行了模拟各种测距误差来源和通过基于数学模型的测距精度仿真。
Using simple method of implementation, SBM achieves decoding and ranging when data is transmitted. Both decoding and ranging are implemented by obtaining phase difference of pulse doublets. With the analysis of BER performance and ranging performance for SBM, not only ranging accuracy can be improved by using a vector phase comparison technique, but also various error sources are simulated and a simulation of ranging accuracy based on mathematical models is performed.
