Abstract

The Carrier Frequency Offset (CFO) occurs in an LTE-OFDM system due to the mismatched frequencies on the received signal and the local oscillator at the receiver. The reason for this offset is caused due to the Doppler shift resulting in Inter-Carrier Interference (ICI) and Inter-Symbol Interference (ISI) where its performance degrades with an increase in the Bit Error Rate (BER). This paper analyses the BER performance for various modulations with different ranges of frequency offset. The results indicate that for BPSK modulation technique, it provides better BER at null carrier frequency offset when compared to other modulation techniques (QPSK, 8PSK, 16PSK, 32PSK, 64PSK, and 16QAM) and other ranges of offset frequency.
