Signal Processing in the Distributed Raman Fiberwire Sensors

Abstract - The project is intended to cover core issues pertaining to the area of a signal processing inside the fiberwire Raman sensors. The purpose of the proposed research is to test the simplex coding idea for "real" pulses. Here the emphasis is not on perfecting the Raman sensors scheme but rather on refining the digital signal processing. The paper will be arranged as follows: analyzing literature about Raman and fiber optics sensors, description of the simplex coding implementation algorithm, mathematical simulation of the Hadamard matrix considering the switching delay edges and without, conclusion about the work done. As a result, the idea of simplex coding based on Hadamard matrices will be tested and it will be concluded about is it suitable for enhancing the signal-to-noise ratio. The question posed will help to understand the simplex coding nature for various scholars.
