The author examines two basically different approaches to phase and timing recovery problems by means of ML estimation. In one approach, an attempt is made to recover the unknown parameters without reference to any information about the data signal. In the other approach, generally called a data-aided approach the author obtains superior performance by taking advantage of whatever is known at the receiver about the transmitted data signal. A comparison of the performance of these two approaches gives valuable information about what type of recovery scheme should be employed for specific signal formats.
