We consider LTE-Advanced uplink system where user equipment (UE) transmits its data to eNodeB. In the uplink system, demodulation reference signal (DM-RS) is transmitted for the channel estimation on the center symbol of the resource block allocated to the UE. Also, sounding reference signal (SRS) is transmitted on the last symbol of the resource block periodically. In this paper, we propose an improved channel estimation scheme by using the SRS: lease square (LS)-based scheme. Simulation results show that the proposed channel estimation scheme has better performance than the DM-based conventional scheme.

Item Type: Conference or Workshop Item (Paper)
