VERFAHREN ZUR BESTIMMUNG DES VORHANDENSEINS EINES TELEKOMMUNIKATIONSSIGNALS AUF EINEM FREQUENZBAND

摘要

#CMT# #/CMT# The method involves determining an energy vector that comprises components representing energy values of an autocorrelation function of a signal received on a frequency band for an offset time. Correlation elements between the components of the energy vector are calculated. A statistic calculation is performed on the correlation elements for determining a statistic indicator. The statistic indicator is compared with a predetermined threshold for determining the presence of a telecommunication signal on the frequency band. #CMT# : #/CMT# Independent claims are also included for the following: (1) a device for determining the presence of a cyclostationary telecommunication signal on a frequency band (2) a computer program comprising instructions for implementing a cyclostationary telecommunication signal presence determining method. #CMT#USE : #/CMT# Method for determining the presence of a cyclostationary telecommunication signal on a frequency band using a determination device of a communication equipment (all claimed) in cognitive radio field. #CMT#ADVANTAGE : #/CMT# The method determines the presence of any telecommunication signal on the frequency band without requiring prior knowledge of cyclic frequencies of the signal. The method permits testing of entire frequency band in single operation, requires only limited number of signal data, and reduces calculation time required for obtaining a determination result. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart of a cyclostationary telecommunication signal presence determining method.'(Drawing includes non-English language text)'.
