1. A magnetic resonance (MR) system with noise figure minimization for modes of an array of coils, said system comprising: an array of coils, which share impedance; a plurality of preamplifiers receiving a plurality of signals from the array of coils; a plurality of matching circuits impedance matching the array of coils to the plurality of preamplifiers; and, a plurality of receivers oversampling the plurality of preamplified signals at a plurality of different match values.
