This paper studies the codebook design problem for noncoherent
multiple input multiple output (MIMO) communications.
Each codeword in the codebook is considered to be a point in a
In this paper, the codebook design is formulated as an inverse
A new algorithm using reflection matrices is proposed to obtain the
optimal codebook for noncoherent block fading channels where
the channel state information (CSI) is unknown at both the
receiver and transmitter.
The key contribution of this paper is that our algorithm is able to
construct an optimal codebook via a sequence of reflection matrices.
