| Abstract(in English) | It is well known that M-ary/spread spectrum (M-ary/SS) system is superior to direct-sequence spread spectrum system under AWGN, and can achieve high spectral efficiency. On the other hand, however, the main drawback of this system is that the synchronization acquisition is difficult. In this paper, we propose a new synchronization acquisition method. As spreading sequences, a set of orthogonal sequences obtained by repeating Sylvester's expansion operation are used. One strong feature of this proposed scheme is that parallel search can be made with the same amount of hardware complexity as a conventional serial search scheme. The evaluation shows that in case of a 64-ary system, the acquisition is attained within 100T_s, where T_s is symbol duration time, at at normalized 6dB Signal to Noise ratio per one information bit transmitted (E_b/N_0) |
