ABSTRACT In this paper a brief study of channel estimation for MIMO-OFDM system has been described. The demand for high data rates in wireless communication systems is increasing as well the demand for new (communication) services. Expanding of existing services or introducing new services needs a portion in the radio spectrum. The need for reliable, high-throughput, mobile wireless communication technologies has never been greater as increases in the demand for on-the-go access to information, entertainment, and other electronic services continues. Two such technologies, which are at the forefront of current research efforts, are orthogonal frequency division multiplexing (OFDM) and multiple-input multiple-output (MIMO) systems, their union being known simply as MIMO-OFDM. Multi-input and multi-output (MIMO) and orthogonal frequency division multiplexing. (OFDM) have attracted significant attention, and become promising techniques for high data rate wireless communication systems.
