Abstract(in English) | It's necessary to select the most suitable channel to get many access chances in the cognitive radio.When we chose the most suitable channel,Channel occupancy ratio and channel transition ration is suitable parameter to presume a channel connection chance.We have proposed highly accuracy and low complexity measurement for channel occupancy ratio and channel transition ratio.We propose the method to set up a threshold different from a sign judgment in process of updating the likelihood information to which it was given from electric power presumptionlikelihood information is divisible into a low likelihood and high likelihood group by a new threshold. A low likelihood sample is updationg by Using the temporary transition rate obtained from high likelihood information and the next symbol.We assume that this threshold chooses the most suitable threshold accordingly according to SNR.From the simulation,we show the proposed measurement achieves higher accuracy but lower complexity measurement than the conventional ones. |
