Abstract :
A system simulation framework for various low-IF receiver architectures commonly used in Bluetooth is presented. The differences between image reject low-IF and I-Q based low IF are discussed, based on the interference properties and filtering requirements. The trade-offs with respect to IF selection are described. The superior performance of the I-Q based complex low IF receiver is shown. A novel simulation methodology is used to represent the signal spectra with a special emphasize on IF selection.
