Abstract

We propose a novel Spatially-Diverse Point-to-MultiPoint (SDPtMP) approach for the fronthaul, utilizing sharp interleaver filter network instead of traditional splitters. This approach leads to distribution of subcarrier groupings from multiple sources to each antenna site in lossless fashion, offering enhanced functionality and higher energy efficiency as it eliminates the need for signal amplification which complements splitters-based architectures. The proposed architecture enables diverse connectivity among multiple Radio Units of a Radio Access Network through spatial, wavelength and subcarrier degrees of networking. According to the simulation results conducted in this study, the optimal values for the subcarrier baud rate is within the range of 3.125 GHz to 3.5 GHz, when spaced at 4 GHz and confined within the sharp interleavers. The proposed architecture offers an overall capacity of 336Gbps per wavelength and spatial dimension.
