Abstract
This paper proposes a novel manipulated rotating polarization switched quadrature phase shift keying (MR-PS-QPSK) technique, and correlated constant modulus algorithm (CMA). The latter utilizes the correlation between PS-QPSK symbols in X/Y polarizations to lock the phase of outputted X/Y signals. Then the X/Y signals are merged according to recovered switching bit, which suppresses the noise and simplify the subsequent process. A FPGA based platform is built up to implement and test this scheme.
