A ESTIMATION OF EXACTNESS OF CORRELATION DETERMINATION
OF PARAMETERS OF SENTINELS OF OFDM OF SIGNALS IS IN SYSTEMS OF RADIOMONITIRING
V.S. Kuznichenko
Offered the aproximate method estimations to
accuracy of the determination temporary parameter OFDM signal, founded on their
correlation analysis with provision for characteristic cyclic prefix structure. The Aproximation of the spectrum OFDM signal in
frequency area limited on frequency by white noise has allowed to find root-mean-square mistake of the estimation of the
temporary interval to orthogonality. The Way to linearizations to dependencies of the interval to orthogonality and values of the carrying frequencies is
received expression for root-mean-square mistake of the estimation of the value
of the carrying frequencies.
Keywords: OFDM signals, digital sample of the signal, correlation analysis.
