In this paper, the authors estimate the capacity of secondary users spectrum access in a cognitive radio based mobile communication system consisting of one primary transmitter and many primary receivers. Because of the small redundancy of the SINR (Signal to Interference plus Noise Ratio) of primary receivers, secondary users can gain spectrum of primary user at the same time slot of primary transmitter. It will improve the capacity of secondary transmitter with free cost of spectrum. This paper proposes two novel algorithms for secondary spectrum access in mobile adhoc network system and finding channel efficiency for different time interval.
