Dalam sistem komunikasi berbilang input berbilang keluaran (MIMO) konvensional, kebanyakan kaedah pemilihan antena yang dipertimbangkan hanya sesuai untuk sistem uni-polarisasi yang diasingkan secara ruang di bawah saluran pudar Rayleigh dalam keadaan bukan garis penglihatan (NLOS). Terdapat beberapa skema pemilihan antena untuk sistem terkutub silang dalam keadaan LOS dan saluran pudar Ricean, dan tiada skema pemilihan antena untuk saluran MIMO dengan kedua-dua LOS dan NLOS. Dalam kes saluran MIMO praktikal, pengaruh keadaan LOS dan NLOS dalam saluran boleh berubah dari semasa ke semasa mengikut parameter saluran dan pergerakan pengguna dalam sistem. Berdasarkan pengaruh dan keadaan saluran ini, sistem uni-kutub mungkin mengatasi kutub silang. Oleh itu, kita harus mempertimbangkan persekitaran saluran MIMO yang praktikal ini apabila membangunkan skema pemilihan antena. Selain itu, tiada kerja penyelidikan telah dilakukan untuk mengurangkan kerumitan pemilihan antena untuk persekitaran saluran MIMO praktikal seperti ini. Dalam makalah ini, pengurangan kerumitan dalam pemilihan antena dicadangkan untuk memberikan daya pemprosesan yang lebih tinggi dalam persekitaran saluran MIMO yang praktikal. Dalam skema yang dicadangkan, antena terpolarisasi yang sesuai dipilih berdasarkan pengiraan penguraian nilai tunggal (SVD) matriks saluran dan kemudian pemuatan bit adaptif digunakan. Keputusan simulasi menunjukkan bahawa daya tampung sistem boleh dipertingkatkan di bawah kekangan sasaran BER dan jumlah kuasa penghantaran sistem MIMO.

Abstract: In the conventional multi-input multi-output (MIMO) communication systems, most of the antenna selection methods considered are suitable only for spatially separated uni-polarized system under Rayleigh fading channel in non-line of sight (NLOS) condition. There have a few antenna selection schemes for the cross-polarized system in LOS condition and Ricean fading channel, and no antenna selection scheme for the MIMO channel with both LOS and NLOS. In the practical MIMO channel case, influence of LOS and NLOS conditions in the channel can vary from time to time according to the channel parameters and user movement in the system. Based on these influences and channel condition, uni-polarized system may outperform a cross-polarized. Thus, we should consider this kind of practical MIMO channel environment when developing the antenna selection scheme. Moreover, no research work has been done on reducing the complexity of antenna selection for this kind of practical MIMO channel environment. In this paper, reduced complexity in antenna selection is proposed to give the higher throughput in the practical MIMO channel environment. In the proposed scheme, suitable polarized antennas are selected based on the calculation of singular value decomposition (SVD) of channel matrix and then adaptive bit loading is applied. Simulation results show that throughput of the system can be improved under the constraint of target BER and total transmit power of the MIMO system.
