Abstract:
1. A method for encoding, pulse shaping, modulating, and transmitting a signal in a communication system, the method comprising: selecting, by a transmitter control system, an analysis wavelet filter bank that is adaptive and capable of encoding, pulse shaping, and modulating the signal; recursively generating, by the transmitter control system, low-pass and high-pass filters according to the analysis wavelet filter bank; re-ordering the low-pass and high-pass filters according to frequency by the analysis wavelet filter bank, wherein re-ordering the low-pass and high-pass filters includes: selecting values from the signal with the analysis wavelet filter bank; using the selected values for modulating the low-pass and high-pass filters; and combining the modulated low-pass and high-pass filters to output an encoded signal.
