Abstract
In recent years WiMAX and UWB technology emerges, 3GPP is now standardization process for the LTE (long term evolution) in order to guarantee the future competition advantage of existing 3G communication technology. The main targets for LTE include increased data rate、improved spectrum efficiency、improved coverage and reduced latency. In order to increase data rate adopt OFDMA (Orthogonal Frequency Division Multiple Access) and MIMO (Multiple Input Multiple Output) technology, used the SC-FDMA (Single Carrier – Frequency Division Multiple Access) to reduce power consumption at uplink, in the mobility support the ultra-high-mobility can reach 350km/hr. Furthermore, the performance evaluation used the MIMO technology to reduce handover failure for LTE uplink in mobility environment, and then reach better performance so as to will not be cut off at the certain speed.
