Neighboring elements in a receive array can be decoupled by various means. However next nearest neighbors still exhibit substantial inductive coupling, which is usually mitigated through the use of preamplifier decoupling. It is commonly assumed that any remaining coupling effects can be removed by characterizing the coupling through measurement of the noise correlation matrix and application of optimum SNR reconstruction.
