MISOおよびMIMO受信機を同時支援するマルチアンテナシステム

Japanese Patent JP5226719

B2

A method of performing channel estimation at a receiver in a wireless multi-antenna communication system, comprising: obtaining, via a single receive antenna, M received pilot symbols for M sets of T scaled pilot symbols generated with M different vectors of a matrix and transmitted via T transmit antennas, where T is an integer greater than one and M is an integer equal to or greater than T wherein each vector includes T coefficients, and wherein the coefficients in the M vectors are selected to facilitate channel estimation by both receivers with a single antenna and receivers with multiple antennas; and filtering the M received pilot symbols to obtain an estimate of a composite multiple-input single-output (MISO) channel between the T transmit antennas and the single receive antenna.
