Cooperative cognitive systems with orthogonal frequency division multiplexing and frequency hopping
Won Mee Jang, Sakura Sikander · 2017
We propose a cooperative cognitive system. The primary system and the cognitive system inform each other such as synchronization in frequency, phase and time. Primary user (PU) can employ orthogonal frequency division multiplexing (OFDM) modulation and the cognitive user (CU) frequency hopping (FH). We explore the scenario in which the CU and PU share the spectrum simultaneously.
