Method for displaying the modulation error of a multiple carrier signal

摘要: The invention relates to a method for displaying the mean modulation error MERRMS of multiple carrier (OFDM) signal in which: a) square vector is calculated according relation (I) each actual symbol I individual k signal; b) this value mk offset with content storage location memory, said being assigned same k, which comprises number locations as OFDM carrier, (II) (iteration formula) A2k,l+1: new measured (instant l+1) should be filed memory A2; A2k,l: previous l) from mk: Actual k; k: Carrier within spectrum, grows frequency, k=0 ... Kmax; l: symbol, time, 0≤l; c) subsequently these values (III), whereby VM quadratically weighted amplitude all ideal states type, used modulated useful data, and finally, d) then graphically represented carriers an abscissa ordinate diagram.
