摘要:
The wireless receiver of the present invention accommodates dual-carrier Evolved EDGE without significantly impacting existing receiver architectures. The inventive receiver comprises a shared local oscillator and two image-rejecting downconverters. The local oscillator generates a local oscillator frequency between two carrier frequencies of adjacent radio channels. The receiver receives a signal in each of the adjacent radio channels. In a dual-carrier mode, a first image-rejecting downconverter uses the local oscillator frequency to downconvert a first signal received in the first radio channel while rejecting a second signal received in the second radio channel. A second image-rejecting downconverter uses the local oscillator frequency to downconvert the second signal while rejecting the first signal. In a diversity mode, the first and second image-rejecting downconverters use the local oscillator frequency to downconvert the signal received in one of the radio channels while rejecting the signal received in the other radio channel.
