Abstract: The radio system comprises a radio unit and an antenna unit coupled to the radio unit. The antenna unit is physically separate and located remote from the radio unit. The antenna unit further comprises a digital (pre-distortion engine configured to pre-distort a modulated digital data signal; a digital to analog converter configured to convert the pre distorted digital data signal to a pre-distorted analog data signal; and a power amplifier configured to amplify the pre-distorted analog data signal which distorts the pre-distorted analog data signal. The distortion introduced by the power amplifier is opposite to the pre-distortion introduced by the digital pre-distortion engine such that the pre-distortion introduced by the digital pre-distortion engine approximately cancels the distortion introduced by the power amplifier. The radio unit further comprises a coefficient computation engine configured to calculate coefficients used by the digital pre-distortion engine to pre-distort the modulated digital data signal.

Abstract: Embodiments are directed to improving blended GNSS/inertial navigation system tolerance to external GNSS interference. A plurality of RF nulling circuits is coupled to at least two antennas and to the inputs of dual GNSS-receivers. The RF nulling circuits provide phase shift configuration data from RF signals input from the antennas to a virtual antenna position estimator. The virtual antenna position estimator determines virtual antenna positions based on the physical antenna position and the phase shift configuration data from each RF nulling circuit. The virtual antenna position estimator then provides the virtual antenna positions to a navigation system for determining at least one navigation parameter of the vehicle.
