- Abstract
- This paper investigates LTE-Advanced uplink technologies. In order to support several requirements of LTE-Advanced, we propose new architecture and scheduling grant information. The link performance of LTE-Advanced is evaluated by MMSE in the uplink single user spatial multiplexing with two transmit antennas. Our simulation results show that the target peak data rate of LTE-Advanced uplink exceeds 120Mbps for low mobility and 60Mbps for high mobility, respectively. Also the performance of frequency non-contiguous DFT-Spread OFDM (DFT-SOFDM) is almost identical to that of frequency contiguous resource allocation. ©2010 IEEE.
