A novel robust pilot tones arranging pattern for OFDM frequency offset tracing

The paper researches rudimental frequency offset tracing using pilot tones after frequency offset acquisition and presents a new OFDM system pilot tones arranging pattern by introducing the ideas of self inter-carriers interference (ICI) cancellation into frequency offset tracing. The pattern is an improvement of the existing pilot tones arranging patter. Theoretical analysis and simulation results show that the new pattern has greater robustness than existing pattern.
