Problems created by channel noise are:

In a digital communication system, information can be sent over a carrier through changes in its fundamental characteristics. These characteristics, phase, frequency, and amplitude, are modified by the transmitter and must be detected by the receiver. Thus, it is absolutely essential for a receiver to recover the frequency, phase, and symbol timing of the carrier. This process is called carrier recovery and can be implemented through various techniques. Channel noise is one of the largest impairments to carrier recovery and that significant noise can prevent carrier locking from occurring successfully.
