%X Dynamic spectrum access technology aims at improving spectrum utilization by allowing so-called secondary users to transmit in already assigned primary users' bands,provided that no significant amount of interference was generated.Dynamic spectrum access radio devices looked for temporarily unoccupied frequency bands and attempted to communicate in them.This paper proposed two spectrum sharing schemes for dynamic spectrum access system,and both the impact on the primary user's link performance and the trans...
