Abstract: A pilot adjusting system adjusts the power level of the pilot relative to the power level of the input signal. For example, the pilot adjusting system detects the power level of the input signal on the signal path leading to an RF amplifier. In response to the power level of the input signal, the pilot adjusting system adjusts the power level of the pilot signal which is injected into the signal path prior to the RF amplifier. In certain embodiments, the pilot adjuster adjusts the pilot power level to maintain a desired input signal to pilot signal ratio at the input to the RF amplifier for the input signal range of the RF amplifier. As such, if the input signal power level drops 30 dB, the pilot adjuster reduces the power level of the pilot signal by 30 dB, thereby maintaining the input signal to pilot ratio throughout the input range of the RF amplifier.

Abstract: A spread spectrum (SS) pilot extraction system clips the RF carriers before the SS pilot is de-spread and the RF carriers are spread. The clipping of the RF carriers raises the noise level in the spectrum. However, the small increase in the in-band noise level is more than offset by the reduction of the in-band RF noise from spreading the clipped carriers. As a result, the reduction in the in-band noise from spreading the clipped carriers expands the detection range of the de-spread pilot. In doing so, the control circuitry can achieve further cancellation of the pilot and the IMD components. Thus, the SS pilot extraction system for feed forward RF amplifiers improves the spread spectrum pilot extraction and detection at the final output coupler to achieve improved pilot and IMD cancellation.
