| description | Fiber optic communication while drilling can transmit downhole geological and engineering parameter data at high speed, serving as a crucial component of intelligent drilling. However, the complex and highly dynamic downhole environment, characterized by strong vibrations and high temperatures, can lead to random attenuation of light intensity, phase mismatch, and signal distortion, thereby reducing the signal-to-noise ratio of the optical signal. This paper proposes a superposition UEP-Spinal code structure to enhance the noise resistance of signals under low SNR conditions. This structure utilizes Unequal Error Protection and adjusts the duty cycle of the superposition weighting factor P to separately encode the head and tail codes of the signal, simplifying the structural complexity of the tail code and reducing complexity by 2.01dB for the same code length. Meanwhile, it enhances the noise resistance of the head code, reducing the bit error rate by 1.21dB for the same channel capacity, and the overall decoding complexity is reduced by 13.3%. The results demonstrate that the superposition UEP-Spinal code can achieve stable and reliable communication in low SNR environments. |
