Title:
無線通信システムにおける使用のためのノイズ分散推定の方法及び装置
Document Type and Number:
Japanese Patent JP2007513564
Kind Code:
A
Abstract:
A method of noise variance estimation to be performed by a user equipment is proposed, comprising steps of: receiving a signal vector containing training sequence and noise vector transmitted via at least one transmission path; estimating the channel impulse response of each transmission path to construct a channel impulse response matrix, according to the signal vector; calculating the noise variance of the signal vector according to the channel impulse response matrix and the signal vector if the channel impulse response remains mainly unchanged during the special time duration of the training sequence.
