Method of multi-antenna wireless data emission, emitter and receiver using the method

摘要

The invention concerns the domain of wireless communication, and more specifically the 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. The invention proposes a space frequency block code applying some well chosen two by two space frequency block codes to each pair of frequencies k and k+N / 2. The proposed SFBC keep the constant envelope property for each antenna while leading to a good performance by introducing some spatial diversity.
