Abstract
A method, detector and radio unit for non-linear interference detection in a communication system having a victim signal and an offending signal are disclosed. According to one aspect, a method includes determining a magnitude of the victim signal raised to a first power to produce a first signal. The method also includes determining a magnitude of the offending signal raised to a second power to produce a second signal. The first signal and the second signal are correlated to produce an output signal indicative of an extent to which the offending signal interferes with the victim signal.
Claims22
A non-linear interference detection method in a wireless communication system having a victim signal and an offending signal, the method including:
- determining a magnitude of the victim signal raised to a first power to produce a first signal;
- determining a magnitude of the offending signal raised to a second power to produce a second signal;
- and
- correlating the first signal and the second signal to produce an output signal indicative of an extent to which the offending signal interferes with the victim signal.
A non-linear interference detector, comprising:
- a first magnitude determiner configured to determine a magnitude of a victim signal raised to a first power to produce a first signal;
- a second magnitude determiner configured to determine a magnitude of an offending signal raised to a second power to produce a second signal;
- and
- a correlator configured to correlate the first signal and the second signal to produce an output signal indicative of an extent to which the offending signal interferes with the victim signal.
A radio unit configured to detect non-linear interference, the radio unit comprising:
- processing circuitry including a memory and a processor:
- the memory configured to store a correlation result;
- and
- the processor in communication with the memory and configured to:
- determine a magnitude of a victim signal raised to a first power to produce a first signal;
- determine a magnitude of an offending signal raised to a second power to produce a second signal;
- and
- correlate the first signal and the second signal to produce an output signal indicative of an extent to which the offending signal interferes with the victim signal.
A radio unit configured to detect non-linear interference, the radio unit comprising:
- a first magnitude determiner module configured to determine a magnitude of a victim signal raised to a first power to produce a first signal;
- a second magnitude determiner module configured to determine a magnitude of an offending signal raised to a second power to produce a second signal;
- and
- a correlator module configured to correlate the first signal and the second signal to produce an output signal indicative of an extent to which the offending signal interferes with the victim signal.
