27.3 Variable-Number Variable-Band Selection
The pair of 
and 
defined in (27.8) associated with the lth band signature sl is considered as two correlated prioritization scores of the lth band, which are essentially two pieces of information contained in two orthogonal subspaces, 
and Pr. Due to the principle of orthogonality (Poor, 1994), the information in 
generally provides innovations information about the signature vector s with respect to reference signature vector r. Therefore, only the 
in (27.8) is used to rank the bands in Ω according to descending order of its magnitude. The ranked band set resulting from using 
priority can be further broken up into two disjoint sets, 
and
