Abstract :
In this letter, a new blind partial transmit sequence (PTS) scheme in multi carrier code division multiple access (MC-CDMA) systems is proposed. Based on the analysis of the relationship between the dispreading property and side information, this proposed scheme divides the received signal into subblocks, and selects the set of phase factors which provides the maximum power of the combination of dispread subblocks. Simulation results show that the proposed scheme can achieve better BER performance and better frequency efficiency, compared with conventional SI transmitting scheme.
