Abstract
Coding and decoding schemes useful in the context of MIMO (Multiple Input Multiple Output) or MISO (Multiple Input Single Output) communications especially used in conjunction of OFDM-like transmission schemes. A space frequency block code (SFBC) is based on the simultaneous use of two variants of Alamouti codes in the frequency domain, each kind of Alamouti code being applied to well-chosen pair of frequencies. The proposed SFBC keeps the constant envelope property for each antenna while leading to performance equal or very close to the pure Alamouti STBC performance.
