Kami mereka bentuk sistem multicarrier bersatu (UMC) untuk komunikasi jalur lebar. Skim yang dicadangkan boleh menyediakan kaedah yang berkesan dan bersatu yang boleh melaksanakan sistem CDMA jalur lebar dengan kecekapan dan fleksibiliti spektrum tinggi kerana pemilihan parameter sistem secara percuma dan penyebaran berganda dalam domain masa dan frekuensi. Selain itu, pengasingan spektrum yang membawa data yang sama untuk memastikan lagi pudar bebas antara subpembawa dilakukan, iaitu, subpembawa dijalin dalam domain frekuensi. Interleaving kekerapan ini mengurangkan kesan ISI dan ICI. Kami juga secara teorinya menganalisis prestasi sistem UMC dengan memperoleh penyelesaian bentuk tertutup untuk kebarangkalian ralat bit dalam saluran pudar Rayleigh terpilih frekuensi. Analisis telah membuktikan bahawa sistem UMC telah mengatasi prestasi sistem CDMA pembawa tunggal konvensional dalam keadaan tertentu.

Abstract: We design a unified multicarrier (UMC) system for wideband communication. The proposed scheme can provide an effective and unified method that can implement a wideband CDMA system with high spectrum efficiency and flexibility because of the free selection of system parameters and a double spreading in the time and frequency domains. Also, separation of the spectrums carrying the same data to further ensure the independent fading between subcarriers is performed, that is, subcarriers are interleaved in the frequency domain. This frequency interleaving mitigates the effect of ISI and ICI. We also theoretically analyze the performance of the UMC system by deriving the closed-form solution for probability of bit error in a frequency selective Rayleigh fading channel. The analysis has proved that the UMC system has outperformed the conventional single carrier CDMA system under given conditions.
