(A) Correlation of two referential signals as a function of coefficient A where nonreferential signals have negative correlation. (B) Correlation of two referential signals as a function of coefficient A where nonreferential signals have positive correlation. Each curve in (A) and (B) was evaluated based on (6), where r, b₁, and b₂ were generated randomly with zero mean and r is not uncorrelated with b₁ and b₂. (C) Mean phase coherence of two referential signals as a function of coefficient A where nonreferential signals have negative correlation. (D) Mean phase coherence of two referential signals as a function of coefficient A where nonreferential signals have positive correlation. Each curve in (C) and (D) was evaluated based on (2), where r, b₁, and b₂ were generated randomly with zero means and r is not uncorrelated with b₁ and b₂. (E) MSC of two referential signals as a function of reference signal power where nonreferential signals have negative cross-power ranging from –0.1 to –1.0 in steps of –0.1. (F) MSC of two referential signals as a function of reference signal power where nonreferential signals have positive cross-power ranging from 0.1 to 1.0 in steps of 0.1. Each curve in (E) and (F) was evaluated based on (13).
