Embodiment Construction
[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0029] The present invention proposes a multi-antenna relay beamforming method based on a decoding and forwarding strategy. In the case where the source node S and the relay node R are configured with multiple antennas, and the destination node D is configured with a single antenna, the effect is very obvious. Using this method, a round of information transmission needs two time slots to complete, and the transmission method is as follows: figure 1 shown, including the following steps:
[0030] S1: In the first time slot, find the beam...
