... utilization of optimal OSA approach is still better than that of TFOSA approach. In (b), both collision probability increase of optimal OSA approach and that of TFOSA approach are more than 0.01 ... per- formances of two approaches: transmit-first OSA (TFOSA) approach and transmit-last OSA (TLOSA) approach. TFOSA means that the secondary user starts to transmit at the first time slot...
