Abstract(in English) In PDM systems, polarization demultiplexing and carrier phase recovery (CPR) are required for signal detection. %This paper proposes a polarization demultiplexing and CPR method based on large-system limit, which is often used for statistical signal detection in wireless communication. %Received symbols in a short time span experience similar states of the channel matrix and phase noise. %To compensates the received symbol at the instant of time $k$, the proposed method utilizes the states at the instant of time $k-w$ to $k-1$. %Next, the matched filter output is calculated by utilizing the estimated transmitted symbol at instant of time $k-w$ to $k-1$. %This matched filter output can be assumed as a multiplication of a normalized Gram matrix os the estimated transmit vector and the transmitted symbol at the instant of time $k$. %The Gram matrix asymptotically approaches a diagonal matrix when $w$ is large enough, thanks to large-system limit, then the transmitted symbol can be detected. %The proposed method can algebraically conduct polarization demultiplexing and CPR with low computational complexity. %As a side effect, this method does not include feedback loops. %
