Claim:
1. A method for generating a communication signal that is decodable according to a first mapping of a first data symbol to a first waveform having a leading edge that is indicative of the first waveform, and a second mapping of a second data symbol to a second waveform having a second leading edge that is indicative of the second waveform, the method comprising: using a circuitry, generating a plurality of data symbols that includes the first data symbol and the second data symbol; modulating, for the first data symbol, a first portion of the communication signal according to the first waveform; modulating, for the second data symbol, a second portion of the communication signal according to a modified second waveform, the modified second waveform having a leading edge that is indicative of the first waveform; transmitting the communication signal over a transmission medium to a remote device; and authenticating the remote device based on a response from the remote device.
