Abstract: Es wird ein LDPC-Code (Paritätsprüfungscode niedriger Dichte) für terrestrischen Cloud-Rundfunk geschaffen. Ein Verfahren zum Codieren eingegebener Informationen auf der Grundlage einer LDPC (Paritätsprüfung niedriger Dichte) enthält das Empfangen von Information und das Codieren der eingegebenen Informationen mit einem LDPC-Codewort unter Verwendung einer Paritätsprüfungsmatrix, wobei die Paritätsprüfungsmatrix eine Struktur aufweisen kann, die durch Kombinieren einer ersten Paritätsprüfungsmatrix für einen LDPC-Code mit einer höheren Coderate als ein Referenzwert mit einer zweiten Paritätsprüfungsmatrix für einen LDPC-Code mit einer niedrigeren Coderate als der Referenzwert erhalten wird.

Abstract: A repeater having different input and output frequencies converts a signal received with the input frequency to a first intermediate frequency signal based on a local oscillating frequency for intermediate frequency conversion, and converts the first intermediate frequency signal to a second intermediate frequency signal by performing digital processing on the first intermediate frequency signal. Then, the repeater generates a first frequency tone signal that corresponds to a difference between the input and output frequencies, and generates a second frequency tone signal from the local oscillating frequency for intermediate frequency conversion and the first frequency tone signal. The repeater up-converts the second intermediate frequency signal to the output frequency based on the second frequency tone signal, and transmits the signal.
