Abstract
Disclosed herein is a wireless communication device which includes an RF processing unit and a baseband unit that carries out carrier tracking based on a signal after RF processing, in which the device includes: a phase error measuring means that measures a phase error estimation value composed of the phase error value of a carrier and the direction thereof; and a phase error correcting means that compares a phase error estimation value with a first threshold value and a second threshold value larger than the first threshold value, and carries out a first or a second phase error correcting process in response to that a phase error estimation value has exceeded the first or second threshold value.

A wireless communication device including an RF processing unit and a baseband unit that carries out carrier tracking based on a signal after RF processing,
- wherein the wireless communication device comprises:
- a phase error measuring means that measures a phase error estimation value composed of the phase error value of a carrier and the direction thereof;
- and
- a phase error correcting means that compares a phase error estimation value with a first threshold value and a second threshold value larger than the first threshold value, and carries out a first or a second phase error correcting process in response to that a phase error estimation value has exceeded the first or second threshold value.
A wireless communication method for carrying out carrier tracking based on a RF received signal, comprising the steps of:
- measuring a phase error estimation value composed of the phase error value of a carrier and the direction thereof;
- comparing a phase error estimation value with a first threshold value and carrying out a first phase error correcting process in response to that a phase error estimation value has exceeded the first threshold value;
- and
- comparing a phase error estimation value with a second threshold value larger than the first threshold value and carrying out a second phase error correcting process in response to that a phase error estimation value has exceeded the second threshold value.
A computer program written in a computer-readable format so as to carry out baseband processing on a digital signal after RF processing on a computer system,
- wherein the computer program includes the steps of:
- measuring a phase error estimation value composed of the phase error value of a carrier and the direction thereof;
- comparing a phase error estimation value with a first threshold value and carrying out a first phase error correcting process in response to that a phase error estimation value has exceeded the first threshold value;
- and
- comparing a phase error estimation value with a second threshold value larger than the first threshold value and carrying out a second phase error correcting process in response to that a phase error estimation value has exceeded the second threshold value.
