Patent ID: 6967945

Claim:
A method of communications in a network using a protocol of pulse transmissions between one master station and one or more user stations, wherein the method comprises the following steps: synchronizing pulse response of the master station received by the user stations; acquiring the pulse responses from the user stations received by the master station; sending pulses close to each other from the master station to the different user stations, and from the different users to the master station; and equalizing the pulses at reception for each user station and for the master station; the equalization step comprising a step of estimation of the parameters of the propagation channel and a step of equalization with sampling at the chip rate, the rate of the associated pulses, the estimation of the parameters of the propagation channel comprising the following steps: a station sends a known sequence of N symbols s ref =[s ref (1), . . . , s ref (N)] T and the signal received by a second station after sampling is expressed as a product of C the encoding matrix of the temporal spread code used by the different users and H the matrix formed by the values of the pulse response h(t) of the channel, sampled at the rate T c y is rewritten in the form y=Sh where S is a matrix whose elements are known and h=[h(1), . . . , h(L)] T with h(n)=h(t)| t=nT c h is estimated with S and y being known, in using a method of equalization.
