OFDMA上行链路频偏干扰消除的所有算法总结 都是很经典的算法-OFDMA uplink frequency offset interference cancellation of all algorithms is very classic algorithm summary

As each user in OFDMA based IEEE 802.16e network has different carrier frequencies, synchronization of carrier frequency offset (CFO) is a very complex task. The hardware implementation of the existing schemes is very expensive. Estimation and compen
