Abstract

An apparatus for converting a signal sampled uniformely in the time domain to a signal sampled in the frequency domain, with certain samples excluded, transmitting the non-uniformly sampled signal and reconverting the transmitted signal to a uniformly sampled signal in the time domain comprises at the transmitter end a delay chain (Fa), a time-frequency converter (TFC), a logic unit (LO) and change-over switch (01) for excluding certain samples by control from the logic unit (LO) and comprises at the receiver end two calculation units (B1 and, respectively, B2) and between the same two identical series connections, each of which includes a delay circuit (F1 and, respectively, F2), a multiplication unit (M1 and, respectively, M2) and an addition unit (S1 and, respectively, S2), of which the first calculation unit (B1) converts frequency samples to amplitude sample, which is fed to one (F1-M1-S1) of the series connections for generating excluded samples, and to phase sample, which is fed to the remaining one (F2-M2-S2) of the series connections, and the second calculation unit (B2) reconverts amplitude sample and phase sample to frequency sample. In a subsequent series connection of delay unit (F3), multiplication unit (M3) and addition unit (S3) the frequency sample is reconverted back to uniformly distributed samples in the time domain.
