Abstract

The invention of multichannel MRS instruments, where additional channels are used for reference measurements of noise has been successful in improving the signal to noise ratio of MRS measurements, but the signal to noise ratio is still inadequate for reliable measurements in many places of interest. To further improve on noise reduction, better methods for dealing with complex noise fields are needed. In available systems the reference channels are connected to a base station by wires. In this paper we argue that by using reference channels with wireless connections to the base station improvements in noise reduction can be expected. We present and discuss a design study of an MRS receiver system using wireless reference channels. The design is based on using as many standard components as possible e.g. GPS disciplined oscillators for time synchronization and WiFi for communication between units.

Key words: Multichannel MRS, noise reduction techniques, wireless sensors, geophysics instrumentation.
