Definitions

  • An example of a multi-carrier transmission method is an Orthogonal Frequency Division Multiplexing (OFDM) system, in which the subtransagers use approximately rectangular pulse shapes.
  • the frequency spacing of the sub-carriers is chosen such that in the frequency space at the frequency at which the signal of a Subtragers is evaluated, the signals of the other Subtrager have a zero crossing.
  • the sub-carriers are orthogonal to each other. Due to the usually very small distance of the sub-carriers and the narrow-band nature of the signals OFDM transmitted on the individual sub-carriers, it is to be ensured that the transmission within the individual sub-carriers is generally not frequency-selective. This simplifies signal equalization at the receiver.
  • the object of the invention is to present efficient methods for transmitting information in a radio communication system, wherein a frequency band split into a plurality of subtransagers is used for the communication. Furthermore, a transmitter and a receiver for carrying out the method will be presented.
  • the information can be determined solely from the knowledge of the frequency positions and the phase relationship, or also that further knowledge is required for this purpose, such as, for example, Knowledge of the amplitude ratio between the at least two signals and / or knowledge of the number of at least two subtragers.
  • Each of the at least two signals may be preferably one of constant phase and amplitude oscillation, i. a non-phase and amplitude modulated oscillation.
  • FIG. 2a shows a first distribution of a frequency band
  • Structure information concerning physical channels e.g. the length of a cyclic prefix of OFDM messages, identification information of the radio cell or of the radio cell sector of the base station BS,
  • the signals ORG 1 and ORG 2 emitted on the two sub-carriers 2 and 5 are sinusoidal oscillations which in themselves do not carry any information, i. their amplitudes are not in accordance with a
  • Base station used scrambling code is to act.
  • there are at least 7 groups of scrambling codes which as well as the frequency ranges according to FIGS 2b are distributed among the base stations BS1, BS2, BS3, BS4, BS5, BS6 and BS7.
  • the frequency ranges for the organization information can already be coded.
  • Allowing different phase differences as a function of the distance between the subcarriers used for the signals ORG1 and ORG2 can be justified as follows: during the signal transmission via the radio channel, the emitted signals are changed, whereby i.a. in a

Abstract

L'invention concerne un procédé de transmission d'informations (ORG) d'un émetteur (BS) à un récepteur (MS) d'un système de radiocommunication. Pour la communication, on utilise une bande de fréquences découpée sur plusieurs sous-porteuses. L'expéditeur (BS) envoie respectivement un signal à au moins deux sous-porteuses, les informations (ORG) étant codées de telle façon qu'elle puissent être délivrées au destinataire par la connaissance de la position en fréquence des deux ou plus sous-porteuses associée à la connaissance des différences de phases entre les deux signaux ou plus. L'invention concerne également un émetteur (BS) et un récepteur (MS) permettant la mise en oeuvre de ce procédé.
