The Impact

This paper investigates the impact of cooperative spectrum sharing policy on the performance of hybrid radio frequency and free space optical wireless communication networks, where primary users and secondary users develop a band of the same spectrum resource. The radio frequency links obey Nakagami-m distribution with arbitrary fading parameter m, while the free space optical link follows gamma-gamma distributed atmospheric turbulence with nonzero pointing error. Because the secondary users access the spectrum band without payment, their behavior needs to be restricted. Specifically, the power of the secondary users is dominated by the tolerable threshold of the primary users. Considering both heterodyne and intensity modulation/direct detection strategies in optical receiver, the performance of optical relaying networks is completely different from that of traditional networks. With the help of bivariable Fox’s H function, new expressions for cumulative distribution function of equivalent signal to noise ratio at destination, probability density function, outage probability, ergodic capacity and symbol error probability are built in closed forms.

Communication System Design

Hybrid free space optical/radio frequency communication systems improve reliability of links. However, independent communication subsystems increase the system complexity, weight, size, and power consumption. Based on microwave photonics, a unified hybrid free space optical/radio frequency communication system design is proposed. The communication subsystems share antenna, modulator, and demodulator to simplify system structure. Operating principle is expounded by theoretical reference, and 3dB theoretical loss is found in millimeter-wave communication mode.
