Abstract

Aspects of the present disclosure are directed to circuits, apparatuses and methods for generating communication signals resistant to early-detect-late-commit attacks. An example embodiment, a plurality of data symbols is generated that includes first and second data symbols. A communication signal is generated that is decodable according to a mapping of the first and second data symbols to respective first and second waveforms. The first waveform has a leading edge that is indicative of the first waveform, and second waveform has a second leading edge that is indicative of the second waveform. In generating the communication signal, a first portion of the communication signal is modulated according to the first waveform for the first data symbol. A second portion of the communication signal is modulated, for the second data symbol, according to a modified second waveform having a leading edge that is indicative of the first wave form.
