Abstract:
1. A space diversity method, comprising: setting an Alamouti-coder-based space frequency block coder as a minimum unit of a space time coder; orthogonally processing the space frequency block coder to acquire transmission signals of part of antenna ports in eight antenna ports, and cyclically delaying the acquired transmission signals of antenna ports to acquire the transmission signals of the rest antenna ports; and each antenna port transmitting the acquired transmission signal in a corresponding time and subcarrier; the step of orthogonally processing the space frequency block coder to acquire transmission signals of part of antenna ports in eight antenna ports, and cyclically delaying the acquired transmission signals of antenna ports to acquire the transmission signals of the rest antenna ports comprises: acquiring the transmission signals of four antenna ports in the eight antenna ports, and multiplying the acquired transmission signals of the four antenna ports by e acquiring the transmission signals of two antenna ports in the eight antenna ports, and multiplying the acquired transmission signals of the two antenna ports by e
