Abstract
A radio frequency (RF) transmitter includes a digital radio processor and a baseband processor. A complex analog-to-digital converter (ADC) within the radio processor provides an analog interface to the baseband processor to receive an analog complex modulated baseband signal and convert the analog complex modulated baseband signal to a digital complex modulated baseband signal. A demodulator within the radio processor demodulates the digital complex modulated baseband signal to recreate the original transmit digital data as a demodulated digital signal. The demodulated digital signal is processed by a digital processor in the radio processor to mitigate the effects of various imperfections in the radio processor circuitry.
