摘要
提出了一种适用于LTE上行SC-FDMA中的判决反馈均衡架构TEDF。依照最小均方误差准则,组成MMSE-TEDF均衡器。在3GPPLTE协议中常用的EVA信道下将这种均衡器进行计算机仿真,结果表明该均衡器在EVA信道下系统性能明显提高。
This paper presented TEDF architecture of decision feedback equalizer for SC-FDMA uplink system of the project LTE. Adopted minimum mean square error principle and composed MMSE-TEDF equalizer. The new equalizer were simulated in EVA channel which is very common in 3GPP LTE protocol. The result shows that the new equalizer improving the ability of the system obviously in EVA channel.
