Novel Architectures for Increasing Communication Link Capacity

Various embodiments are directed to systems and methods for processing signals comprising a first component and a second component. A bandwidth of the first component may be centered at a center frequency. A bandwidth of the second component may be offset from the center frequency by an offset frequency such that at least a portion of the bandwidth of the second component overlaps a skirt of the first component. In various embodiments, a transmitter may split a single signal to generate the first and second components, shift the frequency of the second component, recombine and transmit the two components. Also, in various embodiments, a receiver may receive the signal and derive the first and second components by correcting for cross-interference.
