Demonstration of Inter-Dimensional Adaptive Diversity Combining and Repetition Coding in Converged MMW/FSO Links for 5G and beyond Mobile Fronthaul

We firstly introduce inter-dimensional adaptive-diversity-combining-technique in fiber-wireless fronthaul. By adaptively combining symbols from millimeter-wave and free-space-optics links in time/frequency domain and applying repetition coding, we experimentally attained better tunability in power margins with improved reliability.
