摘要： The present disclosure disclose a method including: a transmit end transmits at least two mixed pilot signals to a receive end separately by using at least two physical antennas. The at least two mixed pilot signals are separately obtained after preset pilot signals corresponding to logical antennas in the at least two logical antennas are weighted by using a precoding weight matrix. The transmit sends a first codebook subset restriction instruction to the receive end. The first codebook subset restriction instruction carries a rank indication RANK and at least one precoding matrix index PMI. The transmit end receives a channel quality feedback message that is fed back by the receive end according to downlink channel quality of an equivalent channel of a specified antenna. According to the present invention, a suitable serving antenna is selected for a receive end, thereby improving signal quality.

摘要： An antenna system and a signal transmission method are provided. The antenna system includes: an antenna array and a matching network, where an S parameter matrix of the matching network matches an S parameter matrix of the antenna array and the matching network is configured to perform pre-distortion on a to-be-transmitted signal or de-distortion on a received signal, and the antenna array is configured to transmit the pre-distorted to-be-transmitted signal. According to the antenna system and the signal transmission method provided in this application, pre-distortion may be performed on a signal that needs to be transmitted by the antenna array or de-distortion may be performed on a signal received by the antenna array, so as to configure energy that is coupled from each antenna array element to an adjacent antenna array element, thereby reducing a coupling effect between antenna array elements.
