Abstract:
It is essential to synchronize the receiver and the transmitter during any transmission. In a given receiver, the sensitivity of the synchronization system is usually higher than the sensitivity of the detection system. The performance of the synchronization system and the detection system in a given receiver depends on the signal to noise ratio at the input of the receiver. Phase noise must be carefully considered when applying any signal processing method, which involves synchronization. The effect of amplitude noise on the sensitivity of the receiver is a well-studied subject. On the other hand, the impact of phase noise on the phase synchronization process is not well-studied in literature. In this paper, the effect of phase noise on the Minimum Shift Keying (MSK) modulator is studied. The Bit Error Rate (BER) is used to demonstrate the impact of the different phase noise levels. Based on the simulation results we can conclude that the effect of phase noise on the synchronization system is negligible.
