Method and device for sending signals between a radio frequency circuit and a baseband circuit

摘要

A method of sending a data signal and a clock signal between a radio frequency circuit of a device and a baseband circuit of the device. The method comprises: determining whether at least one of the data signal and the clock signal is disturbing in that it has a harmonic within the radio frequency band. If it is determined that at least one of the data signal and the clock signal is disturbing, the method further comprises: scrambling the at least one disturbing signal to flatten the spectrum thereof for frequencies below the clock frequency FC, setting a respective at least one indicator to indicate that the at least one disturbing signal has been scrambled, and sending the at least one scrambled signal between the radio frequency circuit and the baseband circuit. The method further comprises, subsequent to the step of sending the at least one scrambled signal, descrambling the at least one scrambled signal if the respective at least one indicator is set.

1. A method of sending a data signal and a clock signal between a radio frequency circuit of a device and a baseband circuit of the device, the radio frequency circuit being configured for at least one of transmission and reception of radio signals in a radio frequency band, the clock signal having a clock frequency FC, the method comprising:
determining whether at least one of the data signal and the clock signal is disturbing in that it has a harmonic within the radio frequency band, wherein if it is determined that at least one of the data signal and the clock signal is disturbing, the method further comprises:
scrambling the at least one disturbing signal to flatten the spectrum thereof for frequencies below the clock frequency FC;setting a respective at least one indicator to indicate that the at least one disturbing signal has been scrambled; andsending the at least one scrambled signal between the radio frequency circuit and the baseband circuit, wherein the method further comprises, subsequent to the step of sending the at least one scrambled signal, descrambling the at least one scrambled signal if the respective at least one indicator is set.
