Radio Kognitif ialah teknologi pemboleh maju untuk penggunaan spektrum kosong yang cekap kerana keupayaannya untuk merasakan persekitaran spektrum. Pelbagai kaedah pengesanan telah dicadangkan untuk penderiaan spektrum, yang merupakan fungsi utama dalam melaksanakan radio kognitif. Walau bagaimanapun, kebanyakan kaedah sedia ada meletakkan minat mereka dalam mengesan isyarat TV dan isyarat mikrofon tanpa wayar. Dalam makalah ini, kami menerokai keberkalaan subpembawa perintis yang sama jaraknya dalam isyarat OFDM. Simulasi dalam pelbagai persekitaran pudar menunjukkan bahawa kaedah pengesanan berasaskan siklostasionari yang dicadangkan berfungsi dengan baik untuk isyarat OFDM.

Abstract: Cognitive Radio is an advanced enabling technology for efficient utilization of vacant spectrum due to its ability to sense the spectrum environment. Various detection methods have been proposed for spectrum sensing, which is the key function in implementing cognitive radio. However most of the existing methods put their interests in detecting TV signal and wireless microphone signals. In this paper, we explore the periodicity of the equally spaced pilot subcarriers in OFDM signal. Simulations in various fading environments show that the proposed cyclostationarity based detection method works well for OFDM signal.
