摘要： A digital broadcast transmitting/receiving system and a signal processing method thereof that can improve the receiving performance of the system. A digital broadcast transmitter has a randomizer to randomize an input data stream which has null bytes being inserted at a specified position, a multiplexer to output a data stream formed by inserting specified known data into the position of the null bytes of the randomized data stream, an encoder to encode the data stream outputted from the multiplexer, and a modulator/RF-converter to modulate the encoded data, RF-convert the modulated data and transmit the RF-converted data. The receiving performance of the digital broadcast transmitting/receiving system can be improved even in a multi-path channel by detecting the known data from the received signal and using the known data in synchronization and equalization in a digital broadcast receiver.

摘要： A control signal generation apparatus for use in a digital information signal recording system enables an optimum channel word of two channel words output from two precoders to be recorded on a digital record medium. The control signal generation apparatus compares the same kind of spectrum components from among peak, notch, and dip components detected from the two channel words, and generates a control signal for selecting an optimum channel word. The apparatus includes a gain controller for controlling the gains of integrators used for detecting the peak, notch, and dip components. The gain controller compares the detected peak, notch, and dip components with upper limit and lower limit set reference values, and generates a gain control signal according to the comparison results. Accordingly, the present invention can reduce the amount of required hardware circuitry, compared to the conventional apparatus which adds the peak, notch, and dip components detected from an individual channel word, and then compares the addition results with each other. An automatic gain controller is included which allows the number of the maximum allowable bits to be reduced, and which increases the processing speed of an integrator.
