AN IMPROVED COGNITIVE RADIO RESOURCE ALLOCATION ALGORITHM BASE D ON RELAY COOPERATION
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
In this paper, a resource allocation algorithm is designed in relay cooperative cognitive radio networks. In amplify and forward (AF) cooperative communication mode, the goal of the proposed algorithm is to maximize the system capacity. Under the same conditions, the results of simulation show that the signal to interference ratio (SINR) of relay cooperative is better than non-relay cooperative’s SINR. The transmission power of relay cooperative is less than non-relay cooperation. The relay cooperation is superior to traditional algorithms in convergence rate, the user’s QoS also can be better guaranteed.
