Dalam makalah ini, kami mencadangkan teknik anggaran saluran yang cekap untuk sistem pemultipleksan pembahagian frekuensi ortogon (OFDM) dengan kepelbagaian pemancar. Teknik yang dicadangkan menganggarkan secara unik semua respons frekuensi saluran yang diperlukan dalam sistem OFDM berkod ruang masa menggunakan simbol latihan "jenis sisir". Kerumitan pengiraan teknik yang dicadangkan dikurangkan secara mendadak, berbanding dengan teknik ralat min kuasa dua minimum (MMSE) sebelumnya, disebabkan oleh pemprosesan yang dibuat semua dalam domain frekuensi. Selain itu, beberapa teknik lain untuk mengurangkan kesan hingar rawak dan menjejak variasi saluran dibincangkan untuk meningkatkan lagi prestasi pendekatan yang dicadangkan. Prestasi pendekatan yang dicadangkan ditunjukkan oleh simulasi komputer untuk saluran wayarles mudah alih.

Abstract: In this paper, we propose an efficient channel estimation technique for orthogonal frequency-division multiplexing (OFDM) systems with transmitter diversity. The proposed technique estimates uniquely all channel frequency responses needed in space-time coded OFDM systems using "comb-type" training symbols. The computational complexity of the proposed technique is reduced dramatically, compared with the previous minimum mean-squared error (MMSE) technique, due to the processing made all in the frequency-domain. Also, several other techniques for mitigating random noise effect and tracking channel variation are discussed to further improve the performance of the proposed approach. The performances of the proposed approach are demonstrated by computer simulation for mobile wireless channels.
