Kertas kerja ini membentangkan kaedah gabungan kepelbagaian antena optimum yang dikaitkan dengan penyebarluasan yang menggunakan Minimum Mean Square Error (MMSE) menggabungkan ke atas domain frekuensi dalam saluran pudar selektif frekuensi untuk pautan ke hadapan Orthogonal Frequency and Code Division Multiplexing (OFCDM) akses wayarles, mengikut urutan. untuk mencapai kapasiti pautan radio maksimum. Keputusan simulasi mempertimbangkan pelbagai keadaan saluran perambatan menjelaskan bahawa kaedah penggabungan kepelbagaian antena dengan Penggabungan Gain Sama (EGC) selepas penggabungan MMSE yang digunakan secara meluas berdasarkan anggaran saluran bantuan simbol perintis dan anggaran kuasa gangguan boleh mengurangkan purata tenaga isyarat yang diterima setiap bit. nisbah ketumpatan spektrum kuasa hingar ke latar belakang (Eb/N0) paling banyak, dengan mengambil kira kesan gangguan antara kod. Tambahan pula, kami menjelaskan bahawa purata yang diperlukan diterima Eb/N0 untuk kadar ralat paket purata 10-2 menggunakan skim penggabungan kepelbagaian dengan EGC selepas penyebarluasan dengan gabungan MMSE dipertingkatkan sebanyak kira-kira 0.3 dB berbanding dengan skim penggabungan kepelbagaian dengan EGC sebelum penyebar dengan gabungan MMSE pada bilangan penggandaan kod sebanyak 24 untuk faktor penyebaran 32 dalam 24- laluan saluran pudar Rayleigh.

Abstract: This paper presents an optimum antenna diversity combining method associated with despreading that employs Minimum Mean Square Error (MMSE) combining over the frequency domain in a frequency-selective fading channel for forward link Orthogonal Frequency and Code Division Multiplexing (OFCDM) wireless access, in order to achieve the maximum radio link capacity. Simulation results considering various propagation channel conditions elucidate that the antenna diversity combining method with Equal Gain Combining (EGC) subsequent to the despreading employing MMSE combining based on pilot symbol-assisted channel estimation and interference power estimation can decrease the required average received signal energy per bit-to-background noise power spectrum density ratio (Eb/N0) the most, taking into account the impact of the inter-code interference. Furthermore, we clarify that the required average received Eb/N0 for the average packet error rate of 10-2 employing the diversity combining scheme with EGC after despreading with MMSE combining is improved by approximately 0.3 dB compared to the diversity combining scheme with EGC before despreading with MMSE combining at the number of code-multiplexing of 24 for the spreading factor of 32 in a 24-path Rayleigh fading channel.
