Abstract:
In a wireless communication system, a method for improving the data transmission rate of a data signal communicated on a wireless channel via a wireless transceiver having audio processing functions adapted for communication of an audio voice signal, said method comprising the steps of:a. receiving an unmodulated baseband data signal;b. altering amplitudes of selected frequency components of said baseband data signal to form a pre-conditioned baseband data signal having a predetermined spectral profile, wherein the spectral profile is substantially similar in shape to the spectral profile of an audio voice signal;c. modulating said pre-conditioned baseband data signal to form a modulated pre-conditioned baseband data signal;d. pre-emphasizing the modulated pre-conditioned baseband data signal at the wireless transceiver to form a transmission data signal for transmission on the wireless channel, the transmission data signal having a substantially flat spectral profile; ande. presenting said modulated pre-conditioned baseband data signal to a modulated data input of said wireless transceiver for transmission on the wireless channel.
