Current Orthogonal Frequency Division Multiplexing

By Paulo S. R. Diniz


Abstract—In this work, we discuss the possibility of using precoding as means to mitigate Inter Carrier Interference (ICI) caused by temporal channel variations in Orthogonal Frequency Division Multiplexing (OFDM) systems. Many different precoding schemes have been introduced in the past. However, the promised gains of these techniques are not achievable nor realistic. In this paper, we introduce a practical low-cost precoding technique to mitigate ICI caused by Doppler spread. The gain in terms of Signal to Interference and Noise Ratio (SINR) is 0.5 dB at a velocity of 500 km/h
