Makalah ini menyiasat faktor peningkatan hingar bagi pengesan paksaan sifar dan pengesan maklum balas keputusan untuk saluran Berbilang Input Berbilang Output (MIMO) segerak. Mula-mula ditunjukkan bahawa pengesan maklum balas pemaksaan sifar dan keputusan boleh dilaksanakan dalam bentuk penapis digital vektor, dan faktor peningkatan hingar dengan pengesan boleh dikira dengan mudah dengan menggunakan bentuk penapis digital vektor. Makalah ini kemudiannya menggunakan pengesan maklum balas pemaksaan sifar dan keputusan pada pengesanan isyarat sistem isyarat berbilang pembawa frekuensi bertindih (FOMS). Faktor peningkatan hingar ternormal, yang diberikan sebagai produk peningkatan hingar dan faktor pengurangan lebar jalur, ditunjukkan lebih kecil dengan pengesan maklum balas keputusan daripada pengesan paksaan sifar. Keputusan simulasi komputer yang dijalankan untuk menilai prestasi kadar ralat bit (BER) dengan dua pengesan juga ditunjukkan bersama prestasi BER dengan pengesan saluran demi saluran konvensional.

Abstract: This paper investigates noise enhancement factors of a zero-forcing detector and a decision feedback detector for synchronous Multiple Input Multiple Output (MIMO) channels. It is first shown that the zero-forcing and decision feedback detectors can be implemented in a vector digital filter form, and the noise enhancement factors with the detectors can easily be calculated by using the vector digital filter form. This paper then applies the zero-forcing and decision feedback detectors to the signal detection of a frequency-overlapped multicarrier signaling (FOMS) system. The normalized noise enhancement factor, which is given as a product of the noise enhancement and bandwidth reduction factors, is shown to be smaller with the decision feedback detector than the zero-forcing detector. Results of computer simulations conducted to evaluate bit error rate (BER) performances with the two detectors are also shown together with the BER performance with a conventional channel-by-channel detector.
