Abstract
A wireless communication system with tunable carrier frequency comprises a transmitter, a receiver, a first voltage control oscillator and a second voltage control oscillator. The first voltage control oscillator is adapted for a local oscillator of the transmitter, and the second voltage control oscillator is adapted for a local oscillator of the receiver, wherein the oscillating frequency of both the first and the second voltage control oscillators is adjustable so as to form a multi channel wireless communication system. The present invention also provides a method with tunable carrier frequency.
