Abstract: A coding and modulation apparatus and method are presented. The apparatus (10) comprises an encoder (11) that encodes input data into cell words, and a modulator (12) that modulates said cell words into constellation values of a non-uniform constellation. The modulator (12) is configured to use, based on the total number M of constellation points of the constellation, the signal-to-noise ratio SNR in dB and the channel characteristics, a non-uniform constellation from a group of constellations comprising one or more of predetermined constellations defined by the constellation position vector u1 . . . v, wherein v=sqrt(M)/2−1.

Abstract: The present invention relates to an apparatus and a corresponding method for mapping error correction code encoded time-domain data of at least two mapping input data streams (S1, S2, . . . , Sn) onto a time-domain mapping output data stream (Q) having a frame structure, comprising a data input (102) for receiving said at least two mapping input data streams (S1, S2, . . . , Sn) each being segmented into data blocks (D1, D2, . . . , DN) carrying error correction code encoded data, a data mapper (104) for mapping the data blocks (D1, D2, . . . , DN) of said at least two mapping input data streams (S1, S2, . . . , Sn) onto frames of said mapping output data stream (Q), each frame comprising a number of frame intervals (F1, F2, . . . , FM), wherein the data mapper (104) is adapted for mapping the data blocks (D1, D2, . . . , DN) onto said frame intervals such that each frame interval (F1, F2, . . . , FM) carries sequentially arranged data blocks (D1, D2, . . . , DN) from various mapping input data streams (S1, S2, . . . , Sn) and that within a frame the mapping of data blocks (D1, D2, . . . , DN) from the various mapping input data streams (S1, S2, . . . , Sn) onto frame intervals (F1, F2, . . . , FM) is different from frame interval to frame interval, and a data output (110) for outputting said mapping output data stream (Q).

Abstract: A transmitter for transmitting payload data and emergency information using data symbols in a single-carrier or multi-carrier broadcast system includes a modulator configured to modulate one or more transmission symbols with signaling data for use in detecting and recovering the payload data at a receiver and to modulate one or more transmission symbols with the payload data. An emergency information receiver receives emergency information carrying information of an actual emergency. An emergency information embedder embeds emergency information into one or more transmission symbols, wherein the emergency information is embedded within a predetermined time period after its reception by using a resource used for carrying signaling data and/or payload data if no emergency information shall be transmitted. A transmission unit transmits the transmission symbols.
