摘要: The paper presents a closed-form blind channel estimation scheme for Alamouti's and other orthogonal space-time block codes. Unlike algorithms, the is able to estimate channels, within phase constant, in multiple-input single-output systems, i.e., systems that employ only one receive antenna. matrix estimated from eigenvalue decomposition of fourth order cumulant output signal. performance depends upon accuracy cumulants, thus improve suggested. Using these improved algorithm performs very well slowly fading channels.
