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

Claim 12:
13. A non-transitory computer readable medium, wherein the non-transitory computer readable medium is configured to store non-transitory instructions, and in response to being executed by a computer, the non-transitory instructions cause the computer to:
generate a data signal based on data;
scramble the data signal with a pseudo-random signal to thereby generate a scrambled data signal;
generate an amplitude shift keying (ASK) signal based on the scrambled data signal; and
transmit the ASK signal, wherein the non-transitory instructions that cause the computer to generate the ASK signal based on the scrambled data signal comprises:
perform a time-frequency transformation on the scrambled data signal to thereby generate a frequency domain signal;
filter the frequency domain signal to thereby generate a filtered frequency domain signal;
map the filtered frequency domain signal to a carrier signal;
perform a frequency-time transformation on the carrier signal to thereby generate a frequency-time transformed carrier signal; and
filter the frequency-time transformed carrier signal to thereby generate the ASK signal.
