CHANNEL ESTIMATING METHOD AND MEANS BASED ON ARRAY ANTENNA

摘要

A channel estimating method and means based on array antenna, a data receiving method and device based on array antenna and a data transmission method and system based on array antenna. Therein, the channel estimating method based on array antenna includes: estimating a first channel impulse response according to the received signals and training sequences of the array antenna, therein, the received signals of the array antenna are radio-frequency signals input from several emission sources, and the first channel impulse response includes channel impulse responses of each of emission sources; estimating arrival angles of each of emission sources; enhancing the channel impulse response of emission source in the first channel impulse response by use of the arrival angles of each mission source and obtaining a second channel impulse response; and filtering the first channel impulse response by use of the second channel impulse response.
