In order to improve the spectral efficiency, a constellation design and optimization for simultaneously transmitting information and synchronization sequence is proposed. First we develop a transmission scheme to hide the synchronization sequence in the information transmission. Then, we construct an optimization problem to minimize the bit error rate (BER) with the constraint of acquisition performance requirement. The closed forms of BER and acquisition probability are carefully derived. The simulation results verify that the proposed scheme has a higher spectral efficiency and a better trade off between BER and acquisition performance.
