ABSTRACT:
A method determines a duration of a frame in a time-hopping, impulse radio system. Channel state information of a channel between two transceivers is estimated periodically. A signal to noise and interference ratio is also estimated periodically. The frame duration of the frame is then determined according to the channel state information and the signal to noise and interference ratio.
