Apparatus and method for maximizing frequency offset tracking performance in a digital receiver |
摘要 |
An automatic frequency control loop structure utilizes a dual selection automatic frequency control unit which is coupled to a differential phase unit and a coherent phase unit to provide a frequency corrected received signal output for efficient tracking of frequency offset drift; and a much lower probability of loss of automatic frequency control loop lock. Thus, a signal from a coherent carrier recovery process provides additional benefit by utilization in adjusting frequency offset tracking performance.
