Patent ID: 8259884

Claim:
A method for generating carrier-synchronized signals, said method comprising: applying first and second carrier signals respectively to first and second inputs of a system, at least one of the first and second carrier signals being modulated, the system comprising a first tree network coupled to the first input and a second tree network coupled to the second input, the first and second tree networks having a plurality of internal node pairs, each node pair including a first node on the first tree network and a second node on the second tree network, each node pair being at a different location, and each node pair characterized by a synchronization flight time, and wherein the synchronization flight times of all node pairs of the plurality of internal node pairs are substantially equal; and for each node pair of the plurality of internal node pairs, processing signals of both the first and second nodes of that node pair to generate a corresponding output carrier signal, wherein for each node pair of the plurality of internal node pairs the carrier phase of the output carrier signal for that node pair is a function of the synchronization flight time for that node pair.
