Joint symbol and frame synchronization for direct- detection optical communication systems

الملخص EN

The problem of joint symbol and frame synchronization in direct-detection optical PPM communication systems under the assumption of known slot timing is considered here.

The optimum maximum-likelihood (ML) and sub-optimum rules for this joint symbol and frame synchronization problem are derived.

The reason of Georghiades's (1985) incorrect ML rule is discussed in this paper.
