Patent DE-4330672-A1 (DE)
Title: Method for transmitting digitised television and/or sound radio signals
Inventor: KLANK OTTO DIPL ING
IPC: H04L27/26
Filed: 1993-09-10
Abstract: A method of this type operates with a distribution of the signal streams among a multiplicity of carriers and correspondingly increased symbol length and a synchronisation symbol spread over all carriers. The method is also referred to as OFDM (Orthogonal Frequency Division Multiplex). The object is to develop this method in such a way that only one symbol is required overall for synchronisation and thus more channel capacity is available to transmit the useful information or the error precoding. According to the invention, the power of the signal is zero or virtually zero during part of the synchronisation symbol period and, over a further time segment, a bit formation defined in a temporal sequence and modulated onto a centrally disposed carrier is transmitted instead of an information sequence assigned to the frequencies. This bit formation contains at least one sequence with optimum autocorrelation characteristics (M-sequence, i.e. maximum-length PRN sequence or CAZAC sequence/Constant Amplitude Zero Autocorrelation). The interval between the bits in the sequence corresponds to the time segments used in the (over-)sampling of the OFDM symbols or to a multiple of these time intervals. In particular for HDTV transmission or audio transmission. <IMAGE>

Patent WO-9013825-A1 (WO)
Inventor: DODDRELL DAVID MICHAEL
IPC: G01R33/483
Filed: 1990-04-27
Abstract: Procédé servant à l'enregistrement de spectres de résonance nucléaire d'échantillons comportant au moins deux groupes (CH3, CH) de noyaux du même type dont le déplacement chimique concorde pour l'essentiel, le signal du second groupe (CH) étant supprimé pour la représentation exclusive du signal du premier groupe (CH3). A cet effet, une séquence de quatre impulsions haute fréquence, de préférence des impulsions haute fréquence à 90° (10, 12, 14), est dirigée sur l'échantillon. La première impulsion haute fréquence (10) est une impulsion faible à action sélective sur les noyaux du premier groupe (CH3). La seconde impulsion haute fréquence (12) est une impulsion faible à action sélective sur les noyaux du second groupe (CH) et elle transfère les aimantations des noyaux du premier groupe (CH3) et du second groupe (CH) au moins en partie dans un état de cohérence à quanta multiples. Immédiatement après la seconde impulsion haute fréquence (12), la troisième impulsion haute fréquence (13) est dirigée, au moins sous la forme d'une impulsion forte, sur l'échantillon et réglée de telle manière que la cohérence à quanta multiples soit transformée en un état d'ordre z corrélé. Dans l'intervalle (τHS) entre la troisième impulsion haute fréquence (13) et la quatrième impulsion haute fréquence (14), une impulsion à gradient d'indice magnétique déphasante est appliquée à l'échantillon. La quatrième impulsion haute fréquence (14) est une impulsion faible à action sélective sur les noyaux du premier groupe (CH3). Elle est réglée de telle manière que l'état d'ordre z corrélé soit transformé à nouveau en un état de cohérence à un seul quantum des noyaux du premier groupe (CH3). Le signal de résonance des noyaux du premier groupe (CH3) est en suite détecté.
