Abstract: Sounding reference signal(SRS) is defined in LTE system to acquire the uplink channel information. By SRS-based detection and estimation, uplink channel information can be obtained by the eNode B scheduler to perform resource scheduling for uplink transmission. A robust SRS-based channel estimation algorithm is deduced and especially a novel SINR estimation mothed is proposed in this paper. Finally, simulation results under typical channel scenarios show that the method can ensure the precision of the SINR estimation under various channel situation.
