1. A signal processing apparatus configured to adaptively phase align and combine radio frequency subcarriers, comprising:
(a) at least two first phase aligners each configured to receive a pair of in-phase and quadrature pairs, said first phase aligners further configured to provide automatic gain control and coherent combing of in-phase and quadrature pairs;
(b) a digital cross-connect configured to receive the in-phase and quadrature pairs from said at least two first phase aligners, said digital cross-connect further configured to associate any two in-phase and quadrature pairs; and
(c) at least two second phase aligners configured to receive the in-phase and quadrature pairs of said digital cross-connect, said second phase aligners further configured to provide automatic gain control and coherent combining of the pairs to produce reduced bandwidth output pairs, wherein the reduced bandwidth output pairs provide data transfer with a low probability of undetected error.
