Abstract

The differential 4-quadrature scheme for coherent optical communications is proposed. This system does not need to track the fluctuation of the states of polarizations, which is essential for most other polarization modulation systems. The input message is encoded to the relative position of the present symbol with respect to the reference frame constructed by the previous 3 symbols and the estimated average amplitude of the received symbols is utilized to determine the channel condition. The performance of the particular 4-symbol differential 4-quadrature system is presented
