“…The ability of chaotic carriers to synchronize in a communication system is valid. Recently, Amiri et al have reported the successful experimental research based on generating and transmission of chaotic signals using an optical fiber communication link [29,30,83]. They proposed a system for chaotic signal generation and cancellation using a MRR fiber optic system, where the required signals of single bandwidth soliton pulse are recovered and manipulated using an add/drop system.…”

The first observation of soliton was done by Scott Russel and the first experimental observation of soliton was occurred by using microscope objectives. In 1970s, Hasegawa primed to realize that the NLS equation was appropriate for the calculation of pulse propagation in optical fibers. Microring resonators (MRRs) shaped from nanoscale photonic waveguides. Ring resonators are not used only in optical networks, but they have recently been presented to be used as sensors, filters and biosensors. Chaotic controls have been used in a great number of optical, engineering and biological designed systems. In applications, the stored ultra-short optical signal can be used to generate optical quantum memory. The ability of ultrashort optical soliton signal to synchronize in a communication system is valid. Multi soliton generation becomes an interesting subject when it is used to enlarge the capacity of communication channels.

Using the micro-ring resonator (MRR) system, the single and multi-carriers at frequencies of f(1)=192.898, f(2)=192.990, f(3)=193.1, f(4)=193.315, and f(5)=193.537 THz with a free spectral range (FSR) of 92, 110, 215, and 222 GHz, respectively, are generated to be suitable for a radio-over-fiber (RoF) system based on multi-input multi-output (MIMO) with orthogonal frequency division multiplexing (OFDM). Demonstrated are the concepts of all-optical MIMO signal generation and its transmission over a 50 km single mode fiber (SMF) optical link and an up to 3 m wireless link. Sixty-four multi-carriers are used in the all-optical generation of three MIMO W-Band RF signals, where the single carriers (f(3)-f(5)) transport the signals over the RoF link. The bit error rate (BER) of the overall system performance is discussed; thus, the transmission of MIMO signals is feasible for up to an SMF path 50 km long and a wireless distance of 3 m.

“…We also assume that the PUs transmit on K separate channels such that each PU k transmits on one single channel number k ( k ∈{1, …, K }). This assumption is easily applicable in any Orthogonal Frequency Division Multiple Access‐based primary network (e.g., ). On the other hand, all PUs have the same transmit power

p_{k}^{P U}

and all SUs have equal transmit power p too.…”

New coalition formation game for spectrum sharing in cognitive radio networks

SUMMARY In cognitive radio networks, Secondary Users (SUs) can access the spectrum simultaneously with the Primary Users (PUs) in underlay mode. In this case, interference caused to the licensed users has to be effectively controlled. The SUs have to make spectrum access decisions in order to enhance their quality of service, but without causing harmful interference to the coexisting PUs. In this paper, we propose a cooperative spectrum decision, which enables the SUs to share the spectrum with the PUs more efficiently. Our approach is based on a new coalitional game in which the coalition value is a function of the SUs' spectral efficiencies, the inter‐SUs interference, and the interference caused to the PUs. By applying new Enter and Leave rules, we obtain a stable coalition structure. Simulation results show that the SUs' spectral efficiencies are considerably increased and that the interference caused to the coexisting PU is reduced by about 7.5% as compared to an opportunistic spectrum access scheme. Moreover, the proposed coalitional game results in a more balanced spectrum sharing in the network. Copyright © 2014 John Wiley & Sons, Ltd.
