摘要： One embodiment of the present invention provides a receiver for wireless communication. The receiver includes a demodulator and at least one filtering mechanism coupled to the demodulator, and an analog-to-digital converter (ADC) coupled to the filtering mechanism. The filtering mechanism can be configured to function as a low-pass filter (LPF) or a band-pass filter (BPF), thereby enabling the receiver to function as a direct-conversion receiver or a low-intermediate frequency (low-IF) receiver.

摘要： One embodiment of the present invention provides a system for controlling at least one RF front-end component. During operation, the system receives, at a programmable logic chip from a baseband chip, a command; identifies the RF front-end component based on an address indicated by the command; and sends a control signal included in the command to the identified RF front-end component via the second interface. The programmable logic chip is coupled to the baseband chip via a first interface, and is coupled to the at least one RF front-end component via a second interface.
