Abstract
A method includes calculating first correlation values corresponding to a first symbol duration based on input samples, the input samples being generated from a received signal; calculating phase differences respectively corresponding to the input samples based on the first correlation values and second correlation values corresponding to a second symbol duration preceding the first symbol duration; updating accumulative phase differences respectively corresponding to the input samples based on the phase differences; and detecting a symbol boundary based on the updated accumulative phase differences.
Claims20
A method comprising:
- calculating first correlation values corresponding to a first symbol duration based on input samples, the input samples being generated from a received signal;
- calculating phase differences respectively corresponding to the input samples based on the first correlation values and second correlation values corresponding to a second symbol duration preceding the first symbol duration;
- updating accumulative phase differences respectively corresponding to the input samples based on the phase differences;
- and
- detecting a symbol boundary based on the updated accumulative phase differences.
An apparatus comprising:
