    摘要： In one embodiment, a device for constructing a pilot signal for use in a wireless repeater where the pilot signal is added to a transmit signal includes one or more pilot generators. Each pilot generator generates a carrier pilot signal associated with a single carrier of the transmit signal and the carrier pilot signals generated by the one or more pilot generators are summed to generate the pilot signal. Each of the one or more pilot generators includes a pilot symbol unit providing multiple data symbols having a predetermined data structure as the carrier pilot signal, a pilot scrambler, a filter, a pilot power determination unit, and a cyclic prefix insertion unit for inserting a cyclic prefix to the carrier pilot signal. In another embodiment, the pilot symbol unit providing multiple data symbols in frequency domain as the carrier pilot signal.

    摘要： An RF power amplifier has an RF input port to which an RF input signal is coupled, an RF output port from which an amplified RF output signal is derived. An RF carrier cancellation combiner has a first input coupled to the RF input port and a second input coupled to the RF output port. The carrier cancellation combiner produces an RF error signal representative of RF distortion of a signal flow path through the RF amplifier between the RF input port and the RF output port. To reduce a residual carrier signal in the RF error signal, a wideband autocalibrating correlator correlates a reference signal, representative of the RF input signal, with the RF error signal, producing a control signal, which is coupled to a vector modulator to modify the signal flow path through the RF amplifier. A digital signal processor within the correlator measures DC distortion associated with the multiplier components of the correlator and controllably removes DC distortion from the control signal, so that modification of the signal flow path through the RF amplifier by the vector modulator is controlled with a higher precision, providing maximal carrier cancellation.
