摘要： The invention presented in this document deals with the hardware implementation of the General Prime Factor Algorithm (GPFA) on integrated circuits on the purpose of minimizing both the complexity and the latency. It proposes a device to implement discrete Fourier transforms in a self-sorting and in-place manner for composite sizes that can be factorized into the product of mutually prime numbers, where some or all of these numbers can expressed as the power of a given base number. The described DFT device is able to dynamically changing the size of the DFT between two consecutive transforms. Derivations of the proposed algorithm are presented to further reduce the latency at the expense of an increased complexity.

摘要： The description proposes a method to control an agent (AGT) operating at least one actuator according to commands repeatedly received from a controller (CTLR), said agent receiving repeatedly measurement data from at least one sensor sensing an environment of the actuator, said measurement data defining, at an iteration k, a current state x k n of the actuator's environment resulting from the application by the actuator of a nominal command u k − 1 n at a previous iteration k -1, said nominal command u k − 1 n at previous iteration k -1 being initially:
- computed by the controller (CTLR) based on a current state x k − 1 n of the actuator's environment defined at least by measurement data acquired by the sensor during said previous iteration k -1, and
- transmitted by the controller (CTLR) to the agent (AGT) to be applied by the actuator,
Wherein the controller (CTLR), at each iteration k:
- computes, in addition to said nominal command u k n , a switching command u k + 1 c based at least on the current state x k n at said iteration k, and
- transmits to the agent (AGT) said switching command u k + 1 c along with said nominal command u k n , said switching command u k + 1 c being intended to be used by the agent to operate the actuator in case no command is received by the agent following the application of the nominal command u k n of iteration k.

摘要： To speed up the computation the invention proposes to use two computation cores in parallel to compute a DFT. Data are dispatched between the two cores according to the even and odd lines of the PFA Ruritanian mapping matrix. Separate storage means are used for each core and means are provided to exchange data between the two separate storage means between the radix computation steps.

摘要： The present invention concerns a device for synchronizing a receiver on received preamble symbol modulated by an orthogonal frequency division multiplexing scheme. The device comprises:
- means for executing a coarse synchronization which provides an estimate of a first time offset and fractional frequency offset,
- means for removing the fractional frequency offset from the preamble symbol,
- means for performing an OFDM demodulation on the preamble symbol on which the fractional frequency offset is removed,
- means for removing from the subcarriers of the demodulated preamble symbol the effect of a phase shift keying modulation,
- means for performing an IDFT on the demodulated preamble symbol on which effect of a modulation wherein at least the phase on subcarriers on which preamble symbol is mapped is modified according to the binary information value of the preamble sequence carried by the subcarrier,
- means for determining a second time offset from the output of the inverse discrete Fourier transform,
- means for compensating the effect of the time offset for next received orthogonal division multiplexing symbol using the second time offset.

摘要： It is proposed a method and device for implementing finite impulse response filters, called FIR filters where filtering is applied on finite sets of samples.
This method deals more accurately with the transient mode computation. It is based on a variable width of the filter used to compute the transient mode. Moreover the proposed solution is easy to implement using only L + 1 real or complex multipliers for the stationary mode as well as the transient mode.

摘要： The invention concerns multi-carrier based digital telecommunication systems where the channel is used to transport several data streams according to the frequency division multiple access scheme.
The proposed method concerns a mapping of data on physical resource in a transmission system where data of elementary streams is distributed over several physical resource blocks, and within each resource block in order to get data from a plurality or elementary streams on at least one sub-carrier and at least a symbol time of each physical resource block. This allows to achieve a good diversity of the allocation of the different streams, leading to the advantage, among others, that poor transmission conditions affecting a particular sub-carrier or a particular time duration, will not concentrate its effects on a particular stream.
