Abstract
An integrated cellular switched modem for enhanced cellular data communication by implementing in DSP or Software all baseband processing normally carried out in a cellular radio transceiver within the processor of the single integrated wireless modem. Adjustments are made to EIA/TIA standards for pre-emphasis, de-emphasis, and companding functions implemented by DSP in order to optimize communication for data.
