Intelligent Encoding through OCDM for High Capacity and Connectivity in Wireless 5G and Beyond Networks

Abstract

Multioperator multiservice support over mobile front haul networks would be an important requirement in the evolving 5G Wireless Communication architectures. This in turn dictates the need for high capacity and high connectivity front-haul options. Optical Code Division Multiplexing over Wavelength Division Multiple Access could be one of the most promising system architectures to support the last/first-mile bottleneck of the Mobile Networks. This paper reports a comparison impact of the energy efficiency and electromagnetic radiation effects for a multioperator multiservice OCDM-based Spectrally Amplitude Encoded Analog Radio over Fiber front-haul for a small cell configuration. The WDM multiplexed mm-wave signals at 60GHz and 28GHz and Prime code-based spectral amplitude patterns assigned for conventional services are analyzed and compared with theWavelength Division Multiple Access system of the same kind. The comparison results confirm that the proposed architecture will be a suitable candidate to meet the 5G challenges of Mobile fronthaul Networks.
