Kertas kerja ini memperkenalkan MMSE-AAA jenis pra-FFT kami yang dicadangkan untuk sistem penghantaran paket OFDM untuk menyekat gangguan sporadis. Skim AAA mengawal berat antena untuk meminimumkan ralat min kuasa dua antara isyarat keluarannya bagi dua tempoh dengan bentuk gelombang yang dihantar yang sama dan mengulangi proses pengemaskinian berat dalam simbol OFDM untuk menumpu berat dengan cepat. Prestasi PER purata AAA yang dicadangkan dengan kehadiran isyarat gangguan antara sistem/intra-sistem sporadis dinilai melalui simulasi komputer yang menganggap saluran pudar LOS 12 laluan dan penghantaran bingkai data IEEE 802.11a secara eksponen. Keputusan simulasi menunjukkan bahawa AAA yang dicadangkan secara berkesan boleh menyekat gangguan antara sistem sporadis yang tidak berkaitan dengan masa ketibaannya. Gangguan intra-sistem sporadis juga boleh ditindas oleh AAA yang dicadangkan dengan lebih cekap daripada gangguan antara sistem selagi gangguan itu tiba antara 13% dan 90% daripada tempoh simbol OFDM selepas permulaan simbol OFDM bagi isyarat yang dikehendaki.

Abstract: This paper introduces our proposed pre-FFT type MMSE-AAA for an OFDM packet transmission system to suppress sporadic interference. The AAA scheme controls an antenna weight to minimize the mean square error between its output signals of two periods with identical transmitted waveform and iterates the weight updating process in an OFDM symbol to rapidly converge the weight. The average PER performance of the proposed AAA with the presence of a sporadic inter-system/intra-system interference signal is evaluated through computer simulations that assume an exponentially decaying 12-path LOS fading channel and IEEE 802.11a data frame transmission. Simulation results show that the proposed AAA can effectively suppress sporadic inter-system interference that is irrelevant to its arrival timing. Sporadic intra-system interference can also be suppressed by the proposed AAA more efficiently than inter-system interference as long as the interference arrives between 13% and 90% of the OFDM symbol duration after the beginning of an OFDM symbol of the desired signal.
