The issue of finding a three-tiered spectrum access scheme in the so-called innovation band from 3550 to 3700 MHz for incumbent applications and protection against other priority access licenses (PAL) and general authorized access (GAA) systems has been addressed by the federal communications commission (FCC). The PAL and GAA systems are citizens broadband radio service devices (CBSDs) connected to a spectrum access system (SAS) which controls the spectrum access. The challenge lies in creating an approach, where the CBSDs are able to fulfil interference mitigation (IM) among each other. In this paper, we present the design and results of a hybrid centralized and distributed medium access control (HMAC) scheme for SAS with efficient and self-organized spectrum sharing schemes using machine learning algorithms based on game theory (GT) and reinforcement learning (RL) for GAA CBSDs in an unlicensed spectrum. The system improvement shows how the SAS can assists decision-making algorithms in a minimum intrusive way to fulfill fair interference and channel occupancy compared with state-of-the-art (SoA) schemes, where the SAS uses an interference graph (IG) to solve the channel allocation problem. Moreover, the suggested schemes support the distributed carrier sense multiple access/collision avoidance (CSMA/CA) mechanism to handle adjacent-channel and cochannel interference (ACI, CCI), which opens new perspective for decentralized systems in a SAS context and beyond 5G.

In this paper, we present an integrated fiber and visible light communication (VLC) system with both single and multimode fibers. Before establishing the fiber–VLC link, we implement a fiber link alone and achieve least BER for a particular length of the fiber. This fiber length is taken as an optimum performing link. The main performance measure utilized in this paper is the Bit Error Rate (BER). Optimum performance is achieved at the point of minimum BER. For an optimum performing fiber–VLC link, the dispersion is analyzed and the compensation of chromatic dispersion is done using ideal dispersion compensation Fiber Bragg Grating (FBG). Utilizing the Gray coded input sequence instead of direct binary sequence reduces the BER, since adjacent constellation points will only differ in one bit. The BER results for 16 QAM (Quadrature Amplitude Modulation) and 64 QAM using Orthogonal Frequency Division Multiplexing (OFDM) are compared for both single mode fiber and multimode fiber links. The simulation results show that for Single Mode Fiber–VLC (SMF–VLC) link the dispersion compensation is better when compared to the Multi Mode Fiber–VLC (MMF–VLC) link.

The fifth generation mobile communications (5G) will have several advanced features with respect to the existing 4G LTE. The waveforms proposed for 5G are very much different from those of 4G and 4.5G. It is primarily due to the existing demerits of the 4G/4.5G waveforms. There are also several additional reasons why 5G should have new waveforms. Energy efficiency of 5G technologies are intended to be exemplary. In this paper, we discuss the proposed 5G waveforms and their energy efficiency issues. We compare their overall efficacy in the cellular ambient environments.

In this paper, a compact triple band circular microstrip antenna with modified Cantor fractal slot for DCS (1.71–1.85 GHz), GPS (1.575 GHz), WiMAX (3.3–3.5 GHz), WLAN (5.15–5.35/5.725–5.825 GHz), HiPERLAN2 (5.15–5.35/5.47–5.725 GHz) applications is designed and discussed. The proposed antenna consists of a circular microstrip antenna loaded with a Cantor fractal slot. The branch length of the Cantor fractal slot is varied asymmetrically according to Hamming window function to obtain the triple band operation. Simulation results demonstrate that the proposed antenna resonates in three distinct frequency bands i.e. 1.5–1.8 GHz, 3.3–3.6 GHz, and 4.7–6 GHz centered around 1.66, 3.48, and 5.54 GHz respectively. A peak gain varies from 0.4 to 8.6 dB across the operating bands. An omnidirectional radiation pattern with good isolation level also obtained at all three resonating frequencies. The proposed antenna incorporates three different wireless standards in itself and offers a compact size of $31times 30times 1.6$ mm3 compared to earlier reported antenna structures.

Millimeter Waves (MMWs) operating at 30–300 GHz band, is very encouraging to the next-generation 5G wireless communication systems, supporting data rates of multiple Gbps per user. By using the Four Wave Mixing (FWM), Self-Phase Modulation (SPM) and Cross Phase Modulation (XPM) effects in the Semiconductor Optical Amplifier (SOA) and Erbium Doped Fiber Amplifier (EDFA), the photonic millimeter switching is realized. These effects can reduce the switching crosstalk since the Optical Single Sideband (OSSB) signal occupies the least optical bandwidth. The best operating conditions improve the Sideband Suppression Ratio (SSR) and at the same time reduce the intensity of unintended sideband signal. This leads to a dispersion-free transmission in the optical fiber and improves the data rate as required in 5G communication. In this paper, the wavelength switching of a 9 Gbps QPSK signal carried on the 30 GHz over a spacing of 1.6 nm as a function of probe wavelength of 1548.515 nm and pump wavelength of 1550.115 nm is achieved.

Wavelength Converter (WC) placement in WDM optical network is essential when traffic demand and resource requirement is higher. As the number of WCs increases the blocking of the connection reduces. However, random placement is undesirable since placement of WC at certain nodes reduces blocking probability at higher extent. Random placement not only results in wastage of resources but also put hurdles in wavelength usability. We have investigated that the nodes to be selected for WC placement depends on Routing and Wavelength Assignment (RWA) strategies. Hence, we have proposed an ordered set of optimum node positions of WCs in the network. In addition, we propose that the optimum solution is different for different RWA strategies. We propose that the sequence of optimal positions is common for respective RWA for any number of WCs. We have also proposed that every RWA has different requirement of nodes deployed with WCs.

A dual mode microstrip patch antenna operating at 2.45 GHz is presented in this article. The design and analysis of the proposed antenna with two modes that is on-body and offbody is accomplished by ANSYS HFSS Electromagnetic software. The on-body mode is obtained with the help of square-ring patch, whereas off body mode is achieved with slotted circular patch placed inside the square-ring patch. Both the patch antennas are independently fed, but share a common ground plane among them. Radiation pattern, $S -$parameter, radiation efficiency of the proposed antenna have been presented here. The antenna can be suitable for body area network applications in the industrial, scientific, and medical band(ISM).

Orthogonal Frequency Division Multiplexing (OFDM) is a pertinent multi-carrier modulation approach which is more immune to frequency selective fading. In 5G waveform, in order to reduce the traffic in OFDM based technology, it is significant to re-size the bandwidth. Consequently, a spectrally localized waveform technology called Filtered Orthogonal Frequency Division Multiplexing (F-OFDM), which is primarily an approach to sub-band based filtering is introduced. Each of the different sub-bands can be handled according to the traffic scenario. This work focusses on analyzing the performance of Filtered OFDM and OFDM in terms of Power Spectral Density (PSD) and Bit error rate (BER). The spectral efficiency in F-OFDM is increased by the reduction of out-of-band (OOB) emission. Simulation for the performance analysis of OFDM and F-OFDM in terms of PSD and BER have done in MATLAB. The working of OFDM has carried out in Verilog and the performance of all components is verified by giving different inputs.
