Berdasarkan Teori Kebarangkalian Percuma (FPT), yang telah menjadi cabang penting dalam Teori Matriks Rawak (RMT), satu skema baharu penderiaan jalur frekuensi untuk Radio Kognitif (CR) dalam Direct-Sequence Code-Division Multiple-Access (DS-CDMA). ) rangkaian berbilang pengguna dicadangkan. Tidak seperti kajian terdahulu dalam bidang ini, skema baru tidak memerlukan pengetahuan tentang urutan penyebaran pengguna dan berkaitan dengan tingkah laku bebas asimptotik matriks rawak. Keputusan simulasi menunjukkan bahawa tuntutan asimptotik berlaku walaupun untuk sebilangan kecil pemerhatian (yang menjadikannya mudah untuk topologi yang berubah-ubah masa) mengatasi skema pengesanan tenaga klasik dan skema lain berdasarkan teori matriks rawak.

Abstract: Based on Free Probability Theory (FPT), which has become an important branch of Random Matrix Theory (RMT), a new scheme of frequency band sensing for Cognitive Radio (CR) in Direct-Sequence Code-Division Multiple-Access (DS-CDMA) multiuser network is proposed. Unlike previous studies in the field, the new scheme does not require the knowledge of the spreading sequences of users and is related to the behavior of the asymptotic free behavior of random matrices. Simulation results show that the asymptotic claims hold true even for a small number of observations (which makes it convenient for time-varying topologies) outperforming classical energy detection scheme and another scheme based on random matrix theory.
