摘　　要：This paper derives an approximate formula for probability density function(PDF) of received signal-to-interference-and-noise ratio(SINR) at user terminal when matched filter(MF) is adopted at a base station(BS).This distribution of SINR can be used to make an analysis of average sum-rate,outage probability,and symbol error rate of massive MIMO downlink with MF at BS.From simulation,it is found that the derived approximate analytical expression for PDF of SINR is consistent with the simulated exact PDF from the definition of SINR in medium-scale and large-scale MIMO systems.This paper derives an approximate formula for probability density function （PDF） of received sig- nal-to-interference-and-noise ratio （SINR） at user terminal when matched filter （MF） is adopted at a base station （BS）. This distribution of SINR can be used to make an analysis of average sum-rate, outage probability, and symbol error rate of massive MIMO downlink with MF at BS. From simulation, it is found that the derived approximate analytical expression for PDF of SINR is consistent with the simulated exact PDF from the definition of SINR in medium-scale and large-scale MIMO systems.
