    摘要: Prior to transferring to a radio communication system, at least one data block is encoded according to predetermined quality-of-service requirements with the aid of a first code. Subsequently, the data block, encoded by the first code, is further encoded according to the radio transmission properties of a usable radio transmission source with the aid of a second code.

    摘要: Irregular LDPC codes have a construction which allows one to obtain a number of codes with different length from a single prototype code with a parity check matrix given by H=[Hz Hi], where Hz specifies the well-known zigzag pattern in the corresponding Tanner graph. The parity check matrices for longer codes are obtained as [Hz′Πdiag(Hi, . . . , Hi)], where Hz′ specifies a longer zigzag pattern depending on the number of matrices Hi used, and Π represents some permutation. This allows one to construct the decoder for a longer code by reusing hardware components developed for decoding the prototype code.

    摘要: A method transmits data by radio during which a frequency band is split into a plurality of subcarriers, and a plurality of antennas are used for transmitting. The data are split into a number of elements, which are to be respectively transmitted by each antenna, said number of elements corresponding to the number of subcarriers, whereby for each antenna, each element is respectively assigned to a subcarrier for transmitting, and at least two antennas on at least one subcarrier transmit different elements. Before an OFDM modulation for each antenna, each element is multiplied by an antenna-specific and element-specific factor. Alternatively, after an OFDM modulation for at least one antenna, the time sequence of the time-dependent signal generated on the basis of the OFDM modulation is reordered. A transmitter carries out the method.

    摘要: A method synchronizes a radio communication system divided into radio cells. Data is transmitted in the radio communication system by a multiple access method. Each radio cell thus has a base station for the radio feed of several mobile stations, allocated to the radio cell. A synchronization of the base station is carried out using the received signals from mobile stations in the same radio cell and also in adjacent radio cells. The base station determines at least one pilot signal and signals said pilot signal to the allocated mobile stations in a downwards direction. The allocated mobile stations transmit the signaled pilot signal in an upwards direction to the base station. The base station determines a synchronization value, from the received pilot signals from the radio cell thereof and also from the adjacent radio cells, fro a time synchronization and/or for a frequency synchronization on which the bas station is synchronized.
