1. A computer implemented method of decoding a signal, the method comprising the steps of:
Receiving a signal;
Sampling the received signal to generate an input waveform having magnitude and phase components;
Applying a transform operation to the input waveform to generate a first decoded signal;
and then
Outputting the first decoded signal,
wherein the step of applying a transform operation comprises the steps of:
Pre-processing the input waveform to generate a mirrored inverted waveform;
and then
Applying a continuous wavelet transform to the mirrored inverted waveform to generate the first decoded signal.
