This work presents a comparison between Orthogonal Frequency Division Multiplexing OFDM and Generalized Frequency Division Multiplexing GFDM to evaluate the latency and bit error rate in a Fiber-wireless link in 3.5 GHz band using Software Defined Radio SDR, taking into account its feasibility for the 5G networks in the future.

A novel multi-antenna global navigation satellite system over fiber (GNSS-over-fiber) system with real-time microwave-photonics-based fiber-length-difference monitoring is proposed. In the architecture, GNSS signal transmission from two or more remote antennas to the local processing center is realized based on radio-over-fiber techniques. A novel microwavephotonics-based fiber length measurement scheme is applied to compensate the line bias delay between different GNSS channels due to the fiber-length variation. Then the carrier phase single difference (SD) algorithm, instead of the carrier phase double difference (DD) algorithm, can be used to improve the vertical precision of multi-antenna GNSS system. Experimental results show that the vertical positioning precision with SD algorithm is about 1.3 mm which is 3.15 times better than that with DD algorithm. Meanwhile, the horizontal positioning precision is about 1.5 mm which is on the same level compared with the system with DD algorithm.

Influence of an optical fiber length on nonlinear dynamics of a spin-wave optoelectronic oscillator is investigated. An increase of the signal power level leads to transition from a stable monochromatic oscillations to a chaotic signal generation through a number of bifurcations. Generation of the rectangular pulses, periodic nonlinear pulses, chaotic pulses, and dynamic chaos are observed for the different fiber lengths. Numerical characterization demonstrates increase of the fractal dimension with increasing of the optical fiber length.
