Kertas kerja ini menganalisis prestasi struktur penerima bersama untuk sistem komunikasi DS-CDMA. Untuk mengurangkan kemerosotan prestasi yang tidak diingini disebabkan oleh gangguan capaian berbilang dan masalah hampir jauh dalam persekitaran saluran pudar berbilang laluan, kertas kerja ini mengeksploitasi struktur penerima untuk komunikasi berbilang pengguna yang terdiri daripada penerima beamformer-RAKE dan pengesan berbilang pengguna yang berkaitan dengan hiasan. Struktur penerimaan DS-CDMA yang dicadangkan mengurangkan kemerosotan prestasi yang ditimbulkan daripada peningkatan hingar dan mendedahkan kerumitan pengiraan yang kurang dengan menggunakan penggabung temporal berbilang laluan sebelum mengakses pengesanan penghiasan. Juga teknik penyongsangan Toeplitz blok yang cekap menggunakan polinomial Levinson matriks diperkenalkan untuk mengurangkan lagi beban pengiraan yang dihadapi daripada menggunakan proses pengesanan berbilang pengguna yang berkaitan dengan hiasan seperti biasa. Keputusan simulasi dijalankan untuk menunjukkan prestasi unggul struktur pengesanan berbilang pengguna yang dicadangkan dalam saluran CDMA pudar berbilang laluan.

Abstract: This paper analyses the performance of a joint receiving structure for DS-CDMA communications systems. To reduce undesirable performance degradation due to the multiple access interferences and the near-far problem in multipath fading channel environment, this paper exploits the receiving structure for the multiuser communication composed of a beamformer-RAKE receiver and a decorrelating multiuser detector. The proposed DS-CDMA receiving structure mitigates the performance impairment invoked from the noise enhancement and reveals less computational complexity by utilizing the multipath temporal combiner prior to accessing the decorrelating detection. Also an efficient block Toeplitz inversion technique using the matrix Levinson polynomials is introduced to further diminish the computational burden encountered from applying the decorrelating multiuser detection process as in usual. Simulation results are conducted to demonstrate the superior performance of the proposed multiuser detection structure in multipath fading CDMA channel.
