Self-adapted multi-antenna selection method for broadband wireless access for high-speed railway

摘要

Various embodiments of a self-adapted multi-antenna selection technique based on broadband wireless access network for high-speed railway are provided. Compared with conventional techniques, the proposed strategy adaptively pairs antennas of an antenna array associated with a base station in response to the fast-changing distance between the base station and the antenna array on a high-speed train. The proposed technique achieves a channel matrix with full rank and thereby improves the channel capacity. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

1. A method, comprising:
estimating an approximate distance between a base station and a set of antennas on a moving platform that travels through an area within a wireless communication range of the base station; adaptively selecting a pair of antennas from a plurality of antennas associated with the base station and spaced apart by a respective separation corresponding to the estimated approximate distance between the base station and the set of antennas on the moving platform; and utilizing the selected pair of antennas in wireless communication with the set of antennas on the moving platform.
