摘要:Inter Carrier Interference (ICI) caused by the Carrier Frequency Offset (CFO) and Doppler shifts, highlydisgrace the performance of OFDM system. For OFDM communication system which is a promising technique forhigh data rate transmission, the theoretical BER and CIR are difficult to obtain in presence of ICI. The BER of thereceived signals are very sensitive to Doppler shifts and frequency offsets (reasons of ICI). This paper presents anefficient and improved ICI Self-Cancellation technique. The proposed technique improves the system throughput andreduces the BER. The performance comparison results show that proposed technique has better BER and improvedCIR than standard OFDM and existing sc scheme.
