한광희 석사과정의 "Bidirectional Iterative Tracking (BIT) Scheme for Estimating Spatial Sub-Channel Parameters in Time-Varying Reciprocal MIMO Channels" 가 2004년 10월 11일부터 중국 상해에서 열리는 Global Mobile Congress 2004(GMC2004)에 발표될 예정임을 알려드립니다.

We propose an adaptive scheme tracking singular values and singular vectors in time-varying reciprocal MIMO channels using a series of training sequence without any CSI. It is a bidirectional iterative tracking (BIT) scheme, in which each side of communication computes their own spatial sub-channel parameters, eventually tracking singular values and singular vectors in an iterative manner. The singular values estimated by the BIT scheme can be used directly for a water-filling type of applications and the complexity of the proposed scheme is acceptable compared with the CSI estimation plus SVD algorithm in time-varying MIMO channels.
