    摘要: Provided are a method and apparatus for hierarchical modulation and demodulation in a Digital Multimedia Broadcasting (DMB) system. The method for hierarchical modulation in a digital broadcast signal transmitter includes the steps of: receiving a first broadcast signal and a second broadcast signal from outside, and encoding the broadcast signals by a first method and a second method, respectively; synthesizing the encoded first and second broadcast signals; determining a modulation point using a constellation diagram of an I-Q plane corresponding to the synthesized signal; and hierarchically phase-shift modulating the synthesized signal using the determined modulation point. Here, in the I-Q plane, the modulation point is deviated by a predetermined deviation angle from a phase axis passing through a modulation point of the first broadcast signal and an origin of the I-Q plane.

    摘要: In an orthogonal frequency division multiplexing (OFDM) system, a receiver includes a received signal transformer, a frequency offset estimator and a frequency compensator. The received signal transformer removes from a training symbol a guardtone and a sub-carrier deviated from a mean value of effective sub-carrier signals by over a predetermined value. The frequency offset estimator estimates the frequency offset of the OFDM digital signal and the frequency compensator compensates the frequency offset of received signals by using the estimated frequency offset. Thus, data transmission efficiency can be greatly improved and influence from a frequency-selective noise channel can be minimized. Further, by removing data unnecessary for the frequency offset estimation, the calculation amount can be reduced.
