20090067521 | BLIND ESTIMATION METHOD OF OFDM MODULATION PARATMETERS - The present invention concerns a blind estimation method of at least one temporal modulation parameter of an OFDM signal, in which a plurality of demodulation attempts of said OFDM signal are carried out using a plurality of respective values of this temporal parameter and, for each demodulation attempt, a cost function representative of the entropy of the demodulated signal is calculated, the estimate of said temporal parameter then being obtained as the value of this parameter minimising said cost function. | 03-12-2009 |
20090147831 | METHOD OF MULTIPLE ACCESS COMMUNICATION IN A CENTRALIZED NETWORK BASED ON AN ULTRA WIDEBAND IMPULSE PHYSICAL LAYER - Method of multiple access communication in a centralized network based on an ultra wideband impulse physical layer allowing code-based multiple access, each user being associated with a code, the transmission being performed in an asynchronous manner in a propagation medium with multiple paths. It is characterized in that a criterion is established so as to find the codes of the Nu various users making it possible to minimize the variance of the multi-user interference J | 06-11-2009 |
20110293026 | METHOD FOR THE BLIND ESTIMATION OF OFDM MODULATION PARAMETERS ACCORDING TO A MAXIMUM LIKELIHOOD CRITERION - The present invention relates to a method for blind estimation of at least one parameter of an OFDM signal according to a maximum likelihood (ML) criterion. In one embodiment, the estimation method uses a deterministic maximum likelihood criterion. In another embodiment, the estimation method assumes that the modulation symbols modulating the sub-carriers of the OFDM multiplex are i.i.d. and Gaussian random variables. The estimation of said parameter is carried out while minimizing a cost function depending on the chosen criterion. | 12-01-2011 |
20120128086 | IDENTIFICATION METHOD OF AN OFDM SIGNAL - An OFDM signal identification method in a received signal, wherein the received signal is sampled and cut off into blocks of P samples, each block being subjected to an inverse Fourier transform to obtain a plurality of symbols at a plurality of frequencies. For each frequency of the plurality, the kurtosis of the set of symbols thus obtained at this frequency is calculated, and then it is determined whether the kurtosis has a periodicity in frequency domain from kurtosis values calculated for the frequencies of the plurality, and the presence of an OFDM signal in the received signal is identified if the kurtosis has such a periodicity. | 05-24-2012 |
20130159807 | Method for Retransmitting Fragmented Packets - A method is provided for retransmitting fragmented packets for which a transference of retransmission credit is performed from one fragment onto the next. The method makes it possible to do away with the drawbacks of the methods existing by appreciably improving performance in terms of untransmitted packet rate and by making it possible to configure the distribution of the error probabilities for the fragments of an IP packet. | 06-20-2013 |
