摘要： The present invention concerns a method for estimating, in a communication system, a level of interference plus noise affecting received signals representative of a set of received pilot symbols, characterized in that the method comprises the steps of: dividing the set of received pilot symbols by a corresponding set of pilot symbols, filtering the divided set of received pilot symbols by a filter the coefficients of which are determined from an eigenvector associated with one of the lowest eigenvalues of a channel fading correlation matrix representative of the correlation between the channel coefficients affecting the set of pilot symbols, averaging up the square absolute values of the symbols obtained at the output of the filter in order to estimate the level of interference plus noise affecting the received signals.

摘要： The present invention concerns a method for determining if a handover of a first half-duplex terminal has to be executed from a first to a second base station. The first base station: transfers signal in the cell of the first base station, receiving a message transferred by the first half-duplex terminal in response to the signal transferred by the first base station, the message comprising information relative to quality measurements on the signals transferred by the first and second base stations, receiving a message indicating if the idle period of the cell of the second base station is compatible with the round trip delay of the first half-duplex terminal in the cell of the second base station, determining if a handover of the first half-duplex terminal has to be executed according to the compatibility.

摘要： Methods and apparatus are provided for transmitting and receiving a data stream in a digital video broadcast system. The data stream is segmented into a plurality of segments of the data stream. A frame is generated. The frame includes a preamble section and a data section. The data section carries the data stream, and the preamble section carries signalling information. The frame is transmitted to a receiver. In generating the frame, the data section of the frame is segmented into a plurality of frequency zones, and at least one segment of the data stream is mapped to a frequency zone of the plurality of frequency zones. The signalling information includes first segmentation information of the data stream and second segmentation information of the plurality of frequency zones.

摘要： A method for determining, in a wireless cellular telecommunication network, if a base station can handle a half-duplex terminal. The base station transfers signals in a cell of the base station, and the half-duplex terminal, when being handled by the base station, does not transfer or receive signals during a period of time, called idle period of the cell of the base station. If a characteristic of the terminal is not compatible with the idle period of the cell of the base station, it is determined that the base station cannot handle the terminal.

摘要： An encoder and a decoder employ an encoding scheme corresponding to a parity check matrix which is derivable from a bipartite protograph formed of variable nodes and check nodes, with each variable node corresponding to a codeword symbol position. The protograph has a plurality of groups of nodes, each group of nodes comprising both variable nodes and check nodes. Each of the check nodes in a group is of degree 2 and has connections to two variable nodes in the same group. The protograph also has a plurality of check nodes of degree n, where n is the number of said plurality of groups, wherein each of the plurality of check nodes has a connection to a variable node in each group such that the symbol positions in a codeword are interleaved between the groups of nodes.
