Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method, comprising:
generating a data signal based on data;
scrambling the data signal with a pseudo-random signal thereby generating a scrambled data signal;
generating an amplitude shift keying (ASK) signal based on the scrambled data signal; and
transmitting the ASK signal, wherein the generating the ASK signal based on the scrambled data signal comprises:
performing a time-frequency transformation on the scrambled data signal thereby generating a frequency domain signal;
filtering the frequency domain signal thereby generating a filtered frequency domain signal;
mapping the filtered frequency domain signal to a carrier signal;
performing a frequency-time transformation on the carrier signal thereby generating a frequency-time transformed carrier signal; and
filtering the frequency-time transformed carrier signal thereby generating the ASK signal.
