摘要：Orthogonal Frequency Division Multiplexing (OFDM), because of its resistance to multipath fading, has attracted increasing interest in recent years as a suitable modulation scheme for commercial high-speed broadband wireless communication systems. OFDM can provide large data rates with sufficient robustness to radio channel impairments. Orthogonal frequency division multiplexing (OFDM) is one of the Multi-Carrier Modulation (MCM) techniques that transmit signals through multiple carriers. These carriers (subcarriers) have different frequencies and they are orthogonal to each other. A major problem in OFDM is its vulnerability to frequency offset errors between the transmitted and received signals. In such situations, the orthogonality of the carriers is no longer maintained, which results in Intercarrier Interference (ICI). In this paper interference is reduced by using ICI self cancellation method.
