    Abstract: There is provided a decoder (310) for sequentially decoding a data signal received through a transmission channel in a communication system, the received data signal carrying transmitted symbols, the decoder comprising a symbol estimation unit (311) configured to determine estimated symbols representative of the transmitted symbols carried by the received signal from information stored in a stack, the stack being filled by iteratively expanding child nodes of a selected node of a decoding tree comprising a plurality of nodes, each node of the decoding tree corresponding to a candidate component of a symbol of the received data signal and each node being associated with a predetermined metric, the stack being filled at each iteration with at least some of the expanded child nodes and being ordered by increasing values of the metrics associated with the nodes, the selected node for each iteration corresponding to the node having the lowest metric in the stack. The decoder further comprises a stack reordering activation monitoring unit (313) configured to monitor at least one stack reordering activation condition and, in response to a stack reordering activation condition being verified, to cause the symbol estimation unit to: reduce the metric associated with each node stored in the stack by a quantity, reorder the stack by increasing value of the reduced metric, and remove a set of nodes from the reordered stack so as to maintain a number N of nodes in the reordered stack, the maintained nodes corresponding to the N nodes having the lowest metrics in the reordered stack.

    Abstract: A decoder or a decoding method for decoding a data signal is provided by iteratively constructing a decoding tree comprising nodes, each representing a component of a symbol of a data signal, each iteration comprising, for a current node of the tree stored in the top of the stack; generating a reference child node of the current node from the data signal; from the reference child node, generating a first and second neighbor child nodes by subtracting/adding a positive integer parameter from/to the value of the reference node; storing in the stack three child nodes derived from the reference, first and second neighbor child nodes, the nodes stored in the stack being ordered by increasing values of a node metric; removing the current node stack; selecting the top node of the stack as the new current node. The data signal is estimated from the stack node information.

    Abstract: The present invention relates to a method of simplifying a geometry model, the method comprises: determination (607) of an integral error rating QiS defined as being a function of a sum of the error measures associated with the points of the plurality having a lower associated Morton code than the Morton code associated with the current point; determination (614) if a given set of points of the plurality can be simplified by a new point, the points of the given set all being the points of the plurality having a Morton code associated with one and the same prefix of given length, as a function at least of a difference between: —the integral error measure QlasS determined for the point of the given set having the largest Morton code (las); and—the integral error measure Qini-1S determined for the point of the plurality having an immediately lower Morton code (ini−1) than the smallest Morton code out of the Morton codes associated with the points of the set.

    Abstract: A receiver for Filter Bank Multicarrier frequency spread signals such as FBMC, FBMC/OQAM, OFDM, comprises a linear phase rotation module adapted to introduce a linear phase rotation to a received time domain signal, a discrete Fourier transform and a Finite Impulse response digital filter. The coefficients of the digital filter define a shift of the frequency response of the prototype filter of the receiver, and the coefficients of the digital filter are fixed so as to compensate the linear phase rotation introduced by the filter. The frequency shift introduced may be equal to the reciprocal of a power of two of the modulation sub carrier spacing.
