Abstract:
1. A method of distinguishing polarizations and information about the carrier signals transmitted from a repeating relay, the method comprising: encoding, using an encoder, a first data stream and a second data stream at a repeating relay; modulating, using a modulator, the first and second encoded data streams at the repeating relay; spreading, using a spreader, the first modulated data stream such that a first spread waveform results having first spreading characteristics and the second modulated data stream such that a second spread waveform results having second spreading characteristics, wherein the first spreading characteristics and the second spreading characteristics are different and differentiate the first spread waveform from the second spread waveform; and transmitting from the repeating relay, the first spread waveform as a first spread spectrum carrier signal on a first electromagnetic (EM) polarization and the second spread waveform as a second spread spectrum carrier signal on a second EM polarization different from the first EM polarization.
