Patent ID: 8081699

Claim:
A polarization modulation ultra-wideband (UWB) transmission system, comprising: an antenna system that is configured to emit first and second radiated RF signals that are orthogonally polarized in space when the antenna system is driven by first and second drive signals, respectively; and a transmitter, coupled to the antenna system, that drives the antenna system with the first and second drive signals, the first and second drive signals being configured to cause the first and second radiated RF signals to be orthogonal in time when emitted by the antenna system, the transmitter including: an input for receiving data; and a polarization orthogonal keying (POK) encoder, coupled to the input, the POK encoder imparting a positive or negative polarity to the first drive signal and imparting a positive or negative polarity to the second drive signal, to encode the first and second radiated RF signals with the data.
