ABSTRACT:
A method and system for digital baseband receiver with digital RF/IF/VLIF support in GSM/GPRS/EDGE compliant handsets. The method may comprise receiving an input signal which may be a digital RF signal, IF or VLIF signals, and the input signal may comprise of I and Q components. The serial digital RF signal may be converted to a parallel digital formatted signal, the latter of which may be transferred to an input of a multiplexer. The received IF signal or VLIF signal may be filtered and transferred to the input of the DU which may convert the VLIF signal to a baseband signal by processing the VLIF signal with a CORDIC algorithm. The DU may bypass processing the IF signal. The output of the DU may be transferred to the input of the multiplexer, such that the multiplexer may select the parallel digital formatted signal or the output of the DU.
