Abstract
This TFC models software-defined radio (SDR) processing chains and manages their distributed execution on SDR clouds. We present models of UMTS processing chains for different bit rates. These chains model the digital processing requirements of a transmitter and receiver in the base station.
Therefore, we analyze the users multiplexing in WCDMA because it has implications on the computing resources and its correct management.
We propose different management strategies, implement one and evaluate its correct functionality. The solution we promote is based on defining a ghost function that captures the data flow dependencies between the chip-level and bit-level processing part of WCDMA. The chip-level processing chain
processes signals of multiple users, whereas the bit-level processing chain processes a single user’s signal. The simulations are executed with an appropriate user load, which is part of our investigation.
For the development of this TFC we are provided of a mapping algorithm for the computing resource management in a simulation environment. This algorithm runs a trellis evaluating the costs of the different paths during the mapping process of the signal processing blocks of a processing chain to the distributed computing resources of the multiprocessors platform.
