摘要： The economic efficiency of information coding and transmission depends in particular on the bandwidth and the time required for transmission. In order to code and transmit information in a reliable and economic manner, an additional effective combination code is provided, taking into account the object to be transmitted, for example in the case of telefax in particular the gray tone transmission. A multistage combination code with a constant phase position which precedes or follows the code elements and/or a different number of periods having identical or different durations is used as code, together with an amplitude code. An amplitude stage is used as redundant or quasi-stage for unambiguously identifying determined code combinations. In the case of gray tone coding and telefax transmission, conversion is transferred to the receiver according to the dither process, allowing quicker transmission. In all transmission cases, frequently repeated code elements, code words and lines in succession are condensed and the number of repetitions is coded and transmitted before or after the code elements, the code words or the coded lines.

摘要： A coding of images and originals, for example for telefax and colour television, allows transmission time to be shortened, in particular in the case of black and white digital or numeric longitudinal coding. For that purpose, the same code words for black and white are provided also for different numbers or digits. As discriminating criterion, the input sequence of black and white is used. During coding of several successive white lines, transmission time can be further shortened in that the coded number of white lines is provided before or after the code word for the white line. During gray coding, transmission time is in particular reduced by subdividing the gray scales or binary code words, if necessary with deliberate redundancy, since in this case many characters occur successively and are then transmitted in the same way as the white lines. During colour image transmission, transmission time is further reduced by code multiplexing and if necessary by QAM-based transmission, whereas in addition the PAM-coded information is D.C. biased. The sum alternating current thus varies in phases in the range of 90° only.

摘要： A receiver is a Digital Video Broadcasting-Terrestrial/Handheld (DVB -T/H) receiver. The DVB-T/H receiver comprises a phase error corrector and a channel estimation and equalization element. The phase error corrector rotates a signal in accordance with an estimate of a phase error, e.g., CPE, which is determined as a function of channel state information (CSI) provided by the channel estimation and equalization element.

摘要： According to known information coding processes, channels are condensed by frequency or time multiplexing, at a high cost and requiring a large bandwidth. According to the invention, serially arranged code elements are individually arranged in parallel, then united in a single code word. The safety of transmission is ensured by converting the information into pulse-width modulated pulses and by coding such pulses as half-periods or as periods which are then transmitted in an uninterrupted sequence of positive and negative half-periods.

摘要： The invention relates to AC coding. The phase angle or the duration of pulses are marked by half-periods or periods and are then provided as stages. The aim of the present invention is to flexibly adjust the bandwidths and bit rates. The number of filler elements that are allocated to the active code elements is increased or reduced. Bit rate flexibility is obtained by increasing or reducing the positions or stages or by configuring the code elements of virtual code words in a serial manner in relation to code words for transmitting information, whereby said code elements are arranged in parallel.
