Abstract
A receiver receives at least one radio frequency band. A signal processor separates a signal space associated with the at least one signal in the at least one radio frequency band and a background space associated with interference and noise in the at least one radio frequency band. For a simulation, a memory stores the environment data of the at least one radio system based on the background space under control of the signal processor.
Claims25
A method of collecting data of at least one radio system for a simulation, the method comprising:
- receiving at least one radio frequency band;
- separating a signal space associated with at least one signal in the at least one radio frequency band and a background space associated with interference and noise in the at least one received band, the separating comprising:
- forming at least one impulse response estimate on the basis of the at least one signal having known data;
- forming at least one regenerated signal on the basis of the at least one impulse response estimate and the known data;
- and
- forming environment data as a difference between a received signal and a regenerated signal of the at least one regenerated signal.
A method of performing a simulation of a radio system, the method comprising:
- performing a simulation with stored environment data associated with the radio system based on a background space of a real radio system which is separated from a signal space of the real radio system, the environment data generated by:
- receiving at least one radio frequency band;
- separating a signal space associated with at least one signal in the at least one radio frequency band and a background space associated with interference and noise in the at least one received band, the separating comprising:
- forming at least one impulse response estimate on the basis of the at least one signal having known data;
- forming at least one regenerated signal on the basis of the at least one impulse response estimate and the known data;
- and
- forming environment data as a difference between a received signal and a regenerated signal of the at least one regenerated signal.
A data collector for a simulation of at least one radio system,
- the data collector comprising:
- a receiver;
- a signal processor;
- and a memory, the receiver being configured to receive at least one radio frequency band, the signal processor is being configured to separate a signal space associated with the at least one signal in the at least one radio frequency band and a background space associated with interference and noise in the at least one radio frequency band by:
- forming at least one impulse response estimate on the basis of the at least one signal with known data,
- forming at least one regenerated signal on the basis of the at least one impulse response estimate and the known data, and
- forming environment data as a difference between a received signal and a regenerated signal.
A non-transitory computer readable device embodying computer program instructions thereon that, when executed by a computer, cause the computer to collect data of at least one radio system for a simulation by performing operations comprising:
- receiving at least one radio frequency band;
- separating a signal space associated with at least one signal in the at least one radio frequency band and a background space associated with interference and noise in the at least one received band by:
- forming at least one impulse response estimate on the basis of the at least one signal with known data,
- forming at least one regenerated signal on the basis of the at least one impulse response estimate and the known data, and
- forming environment data as a difference between a received signal and a regenerated signal.
