Performance Analysis of Uplink Distributed Massive MIMO System with Cross-Layer Design over Rayleigh Fading Channel
摘要
Abstract
The performance of uplink distributed massive multiple-input multiple-output(MIMO)systems with cross-layer design(CLD)is investigated over Rayleigh fading channel,which combines the discrete rate adaptive modulation with truncated automatic repeat request.By means of the performance analysis,the closed-form expressions of average packet error rate(APER)and overall average spectral efficiency(ASE)of distributed massive MIMO systems with CLD are derived based on the conditional probability density function of each user's approximate effective signal-to-noise ratio(SNR)and the switching thresholds under the target packet loss rate(PLR)constraint.With these results,using the approximation of complementary error functions,the approximate APER and overall ASE are also deduced.Simulation results illustrate that the obtained theoretical ASE and APER can match the corresponding simulations well.Besides,the target PLR requirement is satisfied,and the distributed massive MIMO systems offer an obvious performance gain over the co-located massive MIMO systems.关键词
