Descripció del contingut i pla d'activitats:
The objective of the project is to develop a Remote Radio Head (RRH) using ZedBoard.
This RRH, will be incorporated to a Cloud-RAN to facilitate the virtualization of radio resources.
The project will consist in developing the software interface between the soundboard and the virtual machine that is executed in the Cloud-RAN. The interface is based on a 1Gb ethernet connection and must be assumed a full duplex connection to support LTE eNodeB maximum throughput.
From the cloud, the created virtual machine will generate, received and visualize the data. The tests will have to check the quality of the generated RF signal and the real-time losses that may occur.
 
Overview (resum en anglès):
The project’s main objective is to develop a Remote Radio Head (RRH) to be used under the cloud radio access networks (C-RAN) concept.

Actually, the wireless market tendency related with infrastructure implementation consist in separating the computing part of base station (BS) from the radiofrequency
part. Therefore, digital signal processing is assumed in a datacenter and under the cloud computing concept. Signal samples are processed there and data streams are send to
the RRH.

The project consist in developing the appropriate software layer in the RRH to interface with the virtual machine (VM) allocated in the data center.

Two different hardware has been considered to implement the RRH. In both, we followed a similar methodology, splitting the software layer in different functional modules and defining well defined implementation steps.

During project development, we addressed several test in order to verify the proper management of the involved board and check the quality and performance of the signal generated or received.
