US 12,756,601 B2 · Cancellation pulse generation with reduced waveform storage to reduce crests in transmission signals

Abstract

An example apparatus described herein to implement cancellation pulse generation includes a first memory storing first subsets of data samples of a single pulse cancellation waveform. The example apparatus includes a second memory storing second subsets of data samples of the single pulse cancellation waveform, the second subsets including different data samples of the single pulse cancellation waveform than the first subsets. The example apparatus includes first circuitry coupled to the first memory and to the second memory in parallel. The example apparatus includes a plurality of buffers. The example apparatus includes second circuitry coupled to the plurality of buffers.

3 more elements

At least one non-transitory computer-readable medium comprising computer-readable instructions to cause at least one processor circuit to at least:

obtain indices corresponding to samples of a pulse cancellation waveform to be used to generate one or more output cancellation pulses, the indices based on one or more locations of one or more peaks of an input signal;
access individual data samples from respective ones of a plurality of memories in parallel based on the indices, the plurality of memories collectively storing a single instance of the pulse cancellation waveform, respective ones of the memories storing respective different subsets of data samples of a pulse cancellation waveform, the respective ones of the memories having respective storage capacities that are smaller than a total number of samples of the single instance of the pulse cancellation waveform;
and
generate the one or more output cancellation pulses based on the accessed individual data samples.
