Dalam kertas ini, kami menerangkan kaedah penyegerakan bingkai untuk sistem modulasi dwi-ortogon. Dalam sistem modulasi dwi-ortogon, beberapa jujukan dwi-ortogon digunakan untuk penghantaran data. Penyegerakan bingkai dalam sistem modulasi dwi-ortogon adalah sukar kerana jujukan yang dihantar boleh menukar setiap bingkai. Dalam kaedah yang dicadangkan, setiap jujukan bi-ortogon terdiri daripada dua jujukan dalam yang berbeza. Setiap jujukan dwi-ortogon mempunyai susunan yang sama bagi dua jujukan dalam yang berbeza. Penerima boleh menjejaki pemasaan bingkai dengan memerhati susunan urutan dalam. Dalam kertas ini, kami menganalisis prestasi kadar ralat bit yang mengambil kira prestasi penjejakan sistem yang kami bangunkan berdasarkan kaedah kami. Kecekapan spektrum sistem yang dicadangkan dalam sistem capaian berbilang pembahagian kod (CDMA) juga disiasat. Hasilnya, kami mendapati bahawa sistem yang dicadangkan adalah berkesan dalam sistem CDMA segerak.

Abstract: In this paper, we describe a frame synchronization method for bi-orthogonal modulation systems. In bi-orthogonal modulation systems, several bi-orthogonal sequences are used for data transmission. Frame synchronization in bi-orthogonal modulation systems is difficult because transmitted sequences can change every frame. In the proposed method, each bi-orthogonal sequence consists of two different inner sequences. Each bi-orthogonal sequence has the same arrangement of two different inner sequences. A receiver can track the frame timing by observing the arrangement of inner sequences. In this paper, we analyze the bit error rate performance that takes into account the tracking performance of a system we developed based on our method. The spectral efficiency of the proposed system in code division multiple access (CDMA) systems is also investigated. As a result, we found that the proposed system is effective in synchronous CDMA systems.
