Abstract

The orthogonal frequency division multiplexing (OFDM) technique is an attractive wireless communication system. In many applications, however, OFDM is very sensitive to frequency errors caused by two destructive effects. One effect is a reduction of signal amplitude; the other is the introduction of intercarrier interference (ICI) from other carriers caused by the loss of orthogonality between subchannels. In order to minimize ICI in OFDM systems, the correlative coding method was proposed. A normalized frequency offset was introduced in order to analyze the performance of the system where subcarrier frequency offset (SCFO) was used to measure the ICI in the system using Matlab software. The result shows that correlative coding OFDM (CCOFDM) can improve the level of the ICI signal compared to OFDM without correlative coding (OFDMWOCC) by about 6.9 dB.
