SNR-Enhanced Fast BOTDA Combining Channel Estimation Technique With Complementary Pulse Coding
We have implemented a BOTDA that combines channel estimation and complementary coding technique for high performance distributed sensing. The use of OFDM-modulated probe reduces the measurement time sharply compared to the classical frequency sweeping technique. Meanwhile, the complementary coding p...
