This paper establishes a unified perception information transmission model for the difference in the number of cognitive radio users in wireless communication network systems. The model can effectively improve the utilization of spectrum resources. At the same time, this paper introduces a cyclic delay full diversity sensing information coding transmission scheme for the security risks of wireless communication networks. We established a system simulation model to compare performance under different correlation coefficients. The study found that the total interference intensity in the cyclic delay diversity system is lower than that of the frequency division duplex and time division duplex. Its antijamming attack capability also becomes stronger accordingly.

In this paper, we tackle a resource allocation problem over multiple fading channels in wireless networks. This problem is investigated in two ways. First, we consider the problem over the whole multiple fading channels altogether with no power constraint. We look for an optimal solution for this problem by considering an offline waterfillling algorithm. Then, we also propose history-based online waterfilling algorithms for this problem. This online algorithm uses the history partially in order to determine a waterfilling level based on that part of history. Then, the online policy applies this history-based determined waterfilling level to transmit data over the time horizon of the problem. The relative performance of the online and offline policies is evaluated for various types of fading channels (Rayleigh, Rician, Nakagami, Weibull) over various time horizons. The numerical results demonstrate these online waterfilling algorithms shows close performance to offline waterfilling algorithms especially for longer time horizons and by using larger portions of history.

The power over fiber (PoF) scheme delivers simultaneous multiband data and feed power transmission via a double-clad fiber (DCF) for bidirectional radio over fiber (RoF) system. The 5G technology demands cell splitting resulting in an increasing number of remote antenna units (RAU). The RAU is conventionally powered by public power lines.The PoF system is the potential candidate to deliver the electrical power required to drive the RAU during the power outage due to natural calamities and disasters. The PoF system may ensure uninterrupted communication during the debacle. In the proposed scheme, the multiband data signals are generated and transmitted through the single-mode (SM) core of the DCF, whereas feed power from a high-power laser diode (HPLD) is transmitted through the inner cladding for which the core-effective area is larger than the SM core. To increase the electric power conversion efficiency, we use six customized photovoltaic converters (PVC) by introducing the back surface reflector beneath the active photovoltaic layer resulting in improved conversion efficiency of 68% at 858 nm operation wavelength. The power transmission loss can be reduced by using more PVC as it reduces the feed power leakage. As a result, the PoF system yields the power delivery of 12.33 W, sufficient to drive an RAU. The complexity of the system is reduced by using multiband signal over a single DCF and carrier reuse for uplink transmission enabling LD-free RAU. This work helps design the power delivery for the RoF system with DCF and achieve a good transmission performance with negligible power penalty.
