Abstract
Method for the estimation of one or more parameters of a propagation channel with a priori knowledge of the signal in a system comprising one or more sensors, wherein the method comprises the following steps: correlating the signal received by the sensor or sensors s(t) with a known signal c(t), selecting a number of samples of the signal obtained after the correlation step, determining the parameters of the channels such as τ and/or θ which enable the most efficient reconstruction of the signals received by using a maximum likelihood method.

Method for the estimation of one or more parameters of a propagation channel with a priori knowledge of the signal in a system comprising one or more sensors, wherein the method comprises the following steps:
- correlating the signal or signals x(t) received by the sensor or sensors with a known signal c(t),
- sampling said signal after correlation at a sampling period Te and selecting a number of samples per concatenation,
- determining at leas tone parameter of the propagation channel such as τ and/or θ which enables the most efficient reconstruction of the signals received by using a maximum likelihood method.
A device for estimating one or more parameters of a propagation channel with a priori knowledge of the signal in a system comprising one or more sensors, the device comprising at least:
- a device adapted to the correlation of the signal received by the sensor or sensors s(t) with a known signal c(t),
- a device adapted to the selection of a number of samples of the signal obtained after the correlation step, and
- a device adapted to the determining of the parameters of the channel by a maximum likelihood method.
