Abstract
A synchronisation symbol detector that comprises two correlation modules and a comparison module. The first correlation module performs one or more correlations between the input signal and a down-converted version of the input signal and generates a first correlation metric from the one or more first correlations. The second correlation module performs one or more second correlations between the input signal and an up-converted version of the input signal and generates a second correlation metric from the one or more second correlations. The comparison module is configured to compare the first correlation metric and the second correlation metric and determine whether the input signal comprises a synchronisation symbol based on the comparison.
Claims20
A synchronisation symbol detector for detecting a synchronisation symbol in an input signal, the detector comprising:
- a first correlation module configured to perform one or more first correlations between the input signal and a down-converted version of the input signal and generate a first correlation metric based on the one or more first correlations;
- a second correlation module configured to perform one or more second correlations between the input signal and an up-converted version of the input signal and generate a second correlation metric based on the one or more second correlations;
- and
- a comparison module configured to determine whether the input signal comprises a synchronisation symbol based on a comparison of the first and second correlation metrics and output an indication of the determination.
A method of detecting a synchronisation symbol in an input signal, the method comprising:
- performing one or more first correlations between the input signal and a down-converted version of the input signal and generating a first correlation metric based on the one or more first correlations;
- performing one or more second correlations between the input signal and an up-converted version of the input signal and generating a second correlation metric based on the one or more second correlations;
- determining whether the input signal comprises a synchronisation symbol based on a comparison of the first and second correlation metrics;
- and
- outputting an indication of the determination.
A non-transitory computer readable storage medium having stored thereon computer readable instructions that, when executed at a computer system, cause the computer system to perform a method of detecting a synchronisation symbol in an input signal, the method comprising:
- performing one or more first correlations between the input signal and a down-converted version of the input signal and generating a first correlation metric based on the one or more first correlations;
- performing one or more second correlations between the input signal and an up-converted version of the input signal and generating a second correlation metric based on the one or more second correlations;
- determining whether the input signal comprises a synchronisation symbol based on a comparison of the first and second correlation metrics;
- and
- outputting an indication of the determination.
