Abstract:
Methods, systems, and devices for wireless communications are described. The described methods, systems, and devices may include sampling an input signal to obtain one or more signal windows. An amplitude of a first sample within a first signal window of the one or more signal windows may be determined to exceed an amplitude threshold. A series of cancellation pulses may be combined with the first sample within the first signal window to obtain a reduced signal, the reduced signal including one or more reduced samples each having an amplitudes within the amplitude threshold. The series of cancellation pulses may be based on a characteristic of the first sample. The reduced signal may then be transmitted. The series of cancellation pulses may be based on, for example, an envelope of the first sample. In some cases, the series of cancellation pulses may be based on a phase of the first sample.
