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)
Cognitive Radio (CR) is an emerging and promising technology which is predicted to solve the problem of spectrum shortage by utilization of the spectrum efficiently by exploiting the licensed spectrum white spaces. Video on demand (VoD) is a very popular present day service. It is a well-known fact, that video on demand internet service needs a large amount(More)
