摘要： An apparatus for signal acquisition of a Global Navigation Satellite System (GNSS) receiver may downsample digitalized satellite signals based on a code resolution, correlate the downsampled satellite signals and oversampled pseudo-random noise (PRN) codes using a block unit based on a size of a matching filter, and may perform FFT of a value output as a correlation result by employing, as M points, a number of blocks used for the matching filter. Also, the signal acquisition apparatus may estimate a coarse Doppler and a code phase of the satellite signals by comparing a power value, calculated based on the M-point fast Fourier transformed value, with a threshold value, and may estimate a fine Doppler using zero-padding based FFT when the satellite signals are successfully acquired.

摘要： A method and device for transmitting data are discussed. In an embodiment of the present invention, a display state of image data for which transmission is requested is checked, and all or part of image data is transmitted depending on the checked state. The image data is downsampled and compressed into N layers having small-size screens, and all or some of the N compressed layers can be transmitted. In an embodiment, when the display state is in a separation display mode, some of the N layers created from image data for each channel for which transmission is requested are transmitted. When the display state is in a 1 channel display mode, all N layers created from image data for a channel for which transmission is requested are transmitted.

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.
