Abstract: A data communication apparatus and method based on OFDMA are provided. In a first user transmitting unit through which a user transmits user information to a base station in units of first symbol blocks each including M symbols, a first encoder generates a first sub-block composed of Mu user symbols for a u-th user by encoding the user information.

Accordingly, data transmission speed can be freely changed, a very small PAR can be provided, influence of the signal interference is greatly reduced, interference occurring between received blocks due to channels can be prevented, and distortion between channels can be effectively compensated for.

Abstract: An apparatus for detecting a phase error for a system such as a CD or a DVD having a multi-level input signal with an irregular zero crossing shift, and a phase locked loop circuit using the same. An A/D converter digitizes a signal read from the CD or the DVD.

An apparatus for detecting a timing error having a tracking function reduces the amount of normal jitter and a dispersion value of the timing error in accordance with a signal to noise ratio.
