Opportunistic relay selection cooperative communication with interference limited
摘要
Abstract
The communication performance of opportunistic relay selection cooperative com-munication under the condition of Nakagami/I.I.D.Nakagami interference limited and total network power constraint is studied.In addition to the influence of noise,shadow and fading,there is also the existence that the transmitted desired signal is interfered by other user sig-nals from the same frequency band which is called co-channel interference(CCI).When the number of users is increasing,a large number of co-frequency interference will replace noise and become the main constraint factor of wireless communication quality.In this case,the wireless communication environment will change from noise-limited environment to interfer-ence limited.Theoretical analysis and simulation results show that,the opportunistic relay selection cooperative communication in the interference limited environment can achieve di-versity gain and resist the influence of co-channel interference through the cooperation be-tween nodes.The communication performance can be further improved by reasonable power allocation.关键词
