学术报告通知报告题目：DesignFactors for Dual-Hop AF Systems With Partial Relay Selection主讲人：Norman C.

Exact closed-form expressions are obtained for the probability density function (PDF) and the cumulative distribution function (CDF) of the instantaneous end-to-end SNR of dual-hop amplify-and-forward (AF) relaying systems with partial relays election, operating over Nakagami-mfading channels. Outage probability and average symbol error probability are calculated using the derived PDF and CDF expressions, and Monte Carlo simulation results are used to verify the results. Exact results permitaccurate comparisons of the performances of dual-hop AF relaying systems without relay selection, and dual-hop AF relaying systems with partial relays election. It is shown that the diversity gain of dual-hop AF systems with partial relay selection is proportional to the minimum of the fading parameter of the source-to-relay link, m1, and the fading parameter of therelay-to-destination fading link, m2, multiplied by the selection pool size, N,i.e. min{m1,Nm2}. It is shown also that although the performance of partialrelay selection systems is improved by increasing the selection pool size, arelay selection pool of more than m1/m2 relays is not of practical benefit. 该讲座为前沿讲座，欢迎全校师生踊跃参加。校学术委员会网络体系构建与融合北京市重点实验室 2014年12月15日主讲人简介.docx http://portal.bupt.edu.cn//html/main/col51/2014-12/15/20141215102028636122853_1.html
