Abstract
A method of opportunistic access to a frequency band dedicated to a synchronous primary network by a secondary user. The frequency band is divided into K independent channels to which an indicator Band an average availabilityare assigned. At each time frame t, the method includes observing, by the secondary user, the channel i having the greatest indicator B(t); and if the channel i is busy, updating the average availabilityof channel i and updating indicator B(t) of the channel as a function of, and if the channel i is free: updating the average availabilityof channel i, transmitting data set up during the frame t on channel i, computing a quality index R(t) of channel i, and updating indicators B(t) of the K channels as a function of the average availabilitiesand R(t).
