7. An apparatus, comprising:
a transceiver; and
a processor coupled to the transceiver;
wherein the processor is configured to:
generate a data signal based on data;
scramble the data signal with a pseudo-random signal to thereby generate a scrambled data signal; and
generate an amplitude shift keying (ASK) signal based on the scrambled data signal, wherein the processor configured 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 thereby generating the ASK signal; and
the transceiver is configured to:
transmit the ASK signal.
