Abstract:
1. Elaboration method of a list of channels detected in a transmission band wherein it comprises: a first measurement step of the reception power for a plurality of frequencies belonging to said band, each measurement separated by a frequency step, and a memorization step of all of the power measurements, a later step of channel detection from the memorized results, a calculation step of calculating the quadratic power on a sliding frequency window and calculating a first standard deviation for all the measurements from a mean elaborated on a sliding window of a number of determined measurements, the detection of a carrier frequency intervening when the first standard deviation calculated for a given frequency is less than a first determined threshold, and a satellite channel selection step among the detected channels in order to elaborate a channel list, the satellite signals having a quadratic power lower than a second determined threshold.
