Title:
通信受信機の等化器に使用するフィルタ係数の計算
Document Type and Number:
Japanese Patent JP4775596
Kind Code:
B2
Abstract:
The present invention provides an equalizer (200) and a method for computing equalizer filter coefficients in a communication receiver. The equalizer filter coefficients are computed on the basis of a real matrix T which is generated from channel estimation vector f, which is derived from the channel estimation inputs.
