Seni bina saluran MIMO berasaskan pemultipleksan pembahagian kod (CDM) adalah cekap dalam mengukur saluran MIMO yang cepat pudar. Makalah ini mengkaji jujukan longgar segerak (LS), CAZAC, Kasami, dan Chaotic sebagai isyarat probing dalam seni bina CDM. Selepas membandingkan prestasi pengukuran saluran antara jujukan, disimpulkan bahawa jujukan LS adalah kod yang paling sesuai untuk isyarat probing. Walau bagaimanapun, kerana jujukan LS mempunyai kelemahan yang ketara kerana bilangan antena pemancar dihadkan kepada kurang daripada 4, kami mencadangkan menggunakan seni bina hibrid yang menggabungkan CDM dengan TDM untuk menyokong bilangan antena pemancar yang lebih besar. Keputusan simulasi menunjukkan bahawa skim yang dicadangkan boleh meningkatkan prestasi pengukuran apabila lebih daripada 4 antena pemancar digunakan.

Abstract: The code division multiplexing (CDM)-based MIMO channel sounder architecture is efficient at measuring fast fading MIMO channels. This paper examines loosely synchronous (LS), CAZAC, Kasami, and Chaotic sequences as probing signals in the CDM architecture. After comparing the performance of the channel measurement among the sequences, it is concluded that the LS sequences are the most appropriate codes for the probing signals. However, because LS sequences have a significant drawback in that the number of transmit antennas is limited to less than 4, we propose using a hybrid architecture combining CDM with TDM for supporting a greater number of transmit antennas. The simulation results show that the proposed scheme can improve the measurement performance when more than 4 transmit antennas are used.
