    摘要: A method and a device for carrier-frequency synchronisation of a vestigial-sideband-modulated received signal (rVSB(t)) with a carrier signal (ej(2π(fT+Δf)t+Δφ)), which is affected by a frequency offset and/or phase offset (Δf, Δφ), estimates the frequency offset and/or phase offset (Δf, Δφ) of the carrier signal (ej(2π(fT+Δf)t+Δφ)) by means of a maximum-likelihood estimation. For this purpose, the vestigial-sideband-modulated received signal (rVSB(t)) is converted into a modified vestigial-sideband-modulated received signal (xVSB′(t′)), which provides time-discrete complex rotating phasors (|xVSB(t′)·ej2πΔf·t′+Δφ), in which only the time-discrete phases (2πΔft′+Δφ) are dependent upon the frequency offset and/or phase offset (Δf, Δφ).

    摘要: A method for clock synchronisation between an amplitude-modulated or phase-modulated received signal (r(t)) and a transmitted signal (s(t)) estimates the timing offset (ε) between the received signal (r(t)) and the transmitted signal (s(t)) by means of a maximum-likelihood method. The maximum-likelihood method in this context is realised by an estimation filtering (S40; S140) dependent upon the transmission characteristic, a subsequent nonlinear signal-processing function (S50; S150) and an averaging filtering (S60, S100; S180, S200). The received signal (r(t)) is especially a modified vestigial-sideband-modulated received signal (rVSB′(t)). The nonlinear signal-processing function (S50; S150) maintains the alternating component in the spectrum of the pre-filtered vestigial-sideband-modulated received signal (vVSB′(t)).

    摘要: The invention relates to a method and a measuring device for determining a characteristic curve of a high frequency transmitter for transmitting a high frequency signal modulated with a modulation signal. A high frequency signal transmitted by the high frequency transmitter is received by a receiving device (16) and samples of a complex value, real baseband signal (MEAS) are generated therefrom. By demodulation of the samples of the real baseband signal (MEAS), a modulation symbol sequence (SYM) is obtained, from which an ideal baseband signal (REF) is simulated as reference signal. The real baseband signal (MEAS) is corrected, a corrected, real baseband signal (MEAS′) is generated and the deviations of the samples of the corrected, real baseband signal (MEAS′) from the samples of the ideal baseband signal (REF) are evaluated.

    摘要: A method and a device for determining a frequency mask disposed above or below a frequency spectrum of a detected signal determines every individual ordinate value of a first envelope curve disposed completely above or below the frequency spectrum as the maximum value or minimum value of a given number of respectively adjacent ordinate values of the frequency spectrum linked to a window function. Following this, each individual ordinate value of a second envelope curve disposed completely above or below the frequency spectrum and completely above or below the first envelope curve is determined as the maximum value or minimum value of a given number of respectively adjacent ordinate values of the frequency spectrum linked to a window function. Finally, a minimum number of ordinate values of the frequency mask from ordinate values of the first and/or second envelope curve disposed completely between the first and second envelope curve is determined, wherein in each case two successive ordinate values of the frequency mask with a maximum horizontal spacing distance within the first and second envelope curve can be reached in a linear manner relative to one another.
