摘      要：正This paper studied the density of demodulation reference signals（DRS） for dual-layer *** the channel estimation performance and DRS overhead were considered by translating both effects into Signal Interference Noise Ratio（SINR）,and then the total effective SINR was *** comparing the total effective SINR of different DRS density,it is proposed that 12 DRS in a resource block gives about balanced performance at dual-layer beamforming.
