In this paper a new channel equalization technique is described based on Scaled Conjugate Gradient Neural Network (SCGNN) for Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM). To estimate the channel in frequency domain, Space Time Block Code (STBC) is used. At the beginning of each transmitted OFDM block the pilot(More)
Orthogonal frequency division multiplexing is a popular modulation technique for fourth-generation (4G) broadband multimedia wireless communication systems. However, for practical communications, the orthogonality between subcarriers may suffer from carrier frequency offset, resulting in intercarrier interference (ICI), which increases an irreducible error(More)
