Orthogonal Frequency-Division Multiplexing (OFDM) can be used in conjunction with a Multiple Input Multiple Output (MIMO) transceiver to increase the diversity gain and/or the system capacity by exploiting spatial domain. The combination of MIMO techniques with OFDM (MIMO-OFDM) is regarded as a promising solution to enhance the data rate of future broadband wireless communication systems. The great finding was that the well-known flat fading MIMO algorithms can be reused on a carrier-by-carrier basis since the channel becomes orthogonal in the frequency domain with OFDM. This reduces the computational effort and makes MIMO-OFDM attractive for mobile applications. The performance of wireless systems is however limited by multipath fading and interference from other users. In MIMO-OFDM systems, instability of transmitter/receiver Radio Frequency (RF) oscillators and the time varying fading channels can destroy the orthogonality of subcarriers. This causes serious Intercarrier Interference (ICI), thus leading to significant system performance degradation which becomes more severe as the normalized doppler frequency increases. ICI is a major performance limiter in MIMO-OFDM systems. The ICI cancellation in MIMO-OFDM system is an active area of research. In this paper, a review of ICI cancellation techniques has been presented.

The prosperous progress of mobile communications has built the main road of the history of wireless communication. The mobile wireless communications progressed from Personal Communication Services/Network (PCS/PCN) to Global System for Mobile Radio Channel (GSM) to General Packet Radio Service (GPRS) to Enhanced Data for Global Evolution (EDGE) to Universal Mobile Telecommunication Systems (UMTS) (better known as 3G) and will continue to evolve to 4G which is under active research. The future mobile communication system with features of high data rate transmission and open network architecture is desired to satisfy the increasing demand for broadband wireless access. The key objectives of next generation wireless communication systems are to provide reliable transmission with high peak data rates ranging from 100 Mb/s for high mobility applications to 1 Gb/s for low mobility applications, high spectrum efficiency up to 10 b/s/Hz and ubiquitous services that can accommodate various radio accesses.

Orthogonal Frequency Division Multiplexing (OFDM) is one of the most promising physical layer technologies for high data rate wireless communications due to its robustness to frequency selective fading, high spectral efficiency, and low computational complexity. OFDM as a modulation technique was first proposed by Chang (1966) of Bell Labs. Weinstein and Ebert (1971) proposed the use of Fast Fourier Transform (FFT) to implement the system practically (Figure 1). However, the advent of fast digital signal processors and Field-Programmable Gate Arrays (FPGAs) in the mid-1990s provided the real opportunity to effectively implement OFDM systems.
