Abstract: According to one general aspect, an apparatus may include a pre-transmission circuit configured to encode a data signal for communication. The apparatus may include a peak-to-average-power ratio (PAPR) controlling circuit configured to set a power level for a level-adjusted data signal. In some embodiments, the PAPR circuit may be configured to set the power level by employing a multi-loop, multi-phase technique, wherein an inner loop employs multiple phases to constrain the PAPR and reduce at least one power-related error condition, and wherein an outer loop updates the power level. The apparatus may include a transmitter circuit configured to transmit the level-adjusted data signal.

Abstract: A method for providing nonlinear self-interference cancellation of a wireless communication device includes: receiving digital samples of an interfering signal having a first sampling rate and a corrupted victim signal having a second sampling rate; generating a kernel vector based on the interfering signal, wherein the kernel vector has terms of nonlinear self-interference; estimating the nonlinear self-interference of the corrupted victim signal using the terms of the nonlinear self-interference; and providing an estimation of a desired signal by cancelling the nonlinear self-interference from the corrupted victim signal.

Abstract: A method and apparatus are provided. The method includes receiving a reference signal from a transceiver, estimating a time offset (TO) of the reference signal in the frequency domain based on a spectral phase ramp introduced by the TO, compensating the TO of the reference signal based on the estimated TO in the frequency domain by applying the spectral phase ramp to the received reference signal, and providing a TO compensated signal of the reference signal.
