Title:
CHANNEL ESTIMATING METHOD AND MEANS BASED ON ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2007/095775
Kind Code:
A1
Abstract:
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.
