Multi-core DSP for base stations: Large and small

The baseband implementation in cellular base stations for the latest standards specification always presents one of the most exacting challenges in real-time digital signal processing. This paper examines a practical approach to multi-core DSP which addresses the limitations of other technologies that are used to solve the problem and how it not only readily scales up to large high-complexity basestations using the latest techniques in multiple access and multiple antenna systems but down to the lowest cost, high volume systems such as "Femtocell".
