    Abstract: A method for the laying out of the infrastructure of a cellular communications network, notably with mobile units, the network being of the type constituted by a plurality of broadcasting transmitters, each broadcasting on its own broadcasting cell, at least certain of the cells being adjacent and having common overlapping zones, a system of management of the network assigning a single broadcasting cell to a given mobile unit at a given time, according to a given broadcasting transmitter assigning method, the method for the laying out consisting in determining the geographical location and the technical characteristics of each of the transmitters of the network in taking account of the conditions of entry/exit and of movement of the mobile units in the overlapping zones. Thus, the coverage of the network is determined dynamically, such as it is seen by the mobile units.

    Abstract: A process for broadcasting conditional access programs which permits a progressive access. Scrambled program data is transmitted along with partial access checking messages and complete access checking messages such that subscribers having a partial access right may descramble portions of the scrambled data corresponding to information regarding only the identity of the conditional access programs, and subscribers having a complete access right may descramble the remainder of the scrambled data and view the conditional access programs. The conditional access programs may be television pictures, radio programs, or data broadcasts.

    Abstract: A decision feedback equalizer device and method for the block transmission of information symbols in which the received noise-affected observation samples are subjected to a whitening of the noise so as to generate whitened-noise observation samples. The current symbol is detected from earlier decided symbols and whitened-noise observation samples. Block transmission of information symbols can thus be performed over a distorting channel in an atmospheric, ionospheric or other environment towards fixed or mobile receivers.

    Abstract: A method for the decoding of digital data obtained according to a convolutional coding and transmitted on a noise-ridden channel aimed at improving the methods of maximum likelihood decoding such as the Viterbi algorithm consisting in associating, with each estimation s(t) of the corresponding source digital element a(t), a weighting coefficient m(t) representing the reliability of the estimation s(t), the estimation s(t) taking account of the values of a first series of L received samples, and the weighting m(t) taking account of the values of a second series of N samples received, N being strictly greater than L. In a preferred embodiment, a second trellis is associated with the standard first decoding trellis, a trace-back being done in the second trellis on two concurrent paths, used to revise the weighting coefficients obtained at output of the first trellis.
