Abstract
A signal analysis method comprising: receiving an input signal, the input signal comprising a symbol sequence; receiving samples of a reference signal based on a known sample rate, the reference signal comprising the same symbol sequence as the input signal; determining symbol points of the symbol sequence based on the samples; determining measurement times based on the symbol points; and determining at least one signal quality parameter at the measurement times, wherein the at least one signal quality parameter is indicative of a signal quality of the input signal. Further, a measurement system is described.
Claims19
A signal analysis method, said signal analysis method comprising:
- receiving an input signal, said input signal comprising a symbol sequence;
- receiving samples of a reference signal based on a known sample rate, said reference signal comprising the same symbol sequence as said input signal;
- determining symbol points of said symbol sequence based on said samples;
- determining measurement times based on said symbol points;
- and
- determining at least one signal quality parameter at said measurement times,
- wherein said at least one signal quality parameter is indicative of a signal quality of said input signal.
A measurement system, comprising:
- a first input configured to receive an input signal, said input signal comprising a symbol sequence;
- a second input configured to receive a reference signal associated with samples based on a known sample rate, said reference signal comprising the same symbol sequence as said input signal;
- and
- a signal analysis circuit configured to:
- determine symbol points of said symbol sequence based on said samples,
- determine measurement times based on said symbol points;
- and
- determine at least one signal quality parameter at said measurement times, wherein said at least one signal quality parameter is indicative of a signal quality of the input signal.
