Bandwidth auto-matching method for MRS signal
Magnetic Resonance Sounding (MRS) is an effective and direct way to detect the underground water. The MRS-FID signal is an extremely weak signal with nV-level and it is often interfered by the various noises. Narrow-band filtering is an effective way to suppress noise and improve the SNR (signal to...

| description | Magnetic Resonance Sounding (MRS) is an effective and direct way to detect the underground water. The MRS-FID signal is an extremely weak signal with nV-level and it is often interfered by the various noises. Narrow-band filtering is an effective way to suppress noise and improve the SNR (signal to noise ratio). However, the bandwidth of narrow-band filtering is usually fixed, and the actual bandwidth of MRS-FID signal varies from place to place. Therefore, different places require different bandwidths for obtaining the better results. This paper proposed a new method, which can improve the narrow band filter performance by using bandwidth auto-matching. The final results show that the proposed method is better than the fixed bandwidth method. |
