Abstract
Interference is a major obstacle in radio communications, especially when opportunistic frequency reuse is an inherent
requirement for maximising spectral ef¿ciency in heterogeneous networks. A typical example is encountered in cellular
communications where macrocell-edge users receive interference from small cell transmissions that use the same radio
frequency band. Innovating interference management algorithms are employed towards this end, which because of their
interdependencies with numerous parameters of the target operating scenario and various low-level implementation
aspects, need to be prototyped in real-time signal processing platforms in order to be credibly veri¿ed. In this paper, we
present the development and experimental validation of a macrocell/femtocell coexistence scenario in close to real-life
conditions. The inclusion of an agile interference management scheme increased the signal processing complexity at
the physical layer. This overhead was appropriately addressed by engaging advanced parallel processing techniques,
optimisations of the arithmetic operations and intelligent reuse of logic and memory resources in the ¿eld programmable
gate array (FPGA)-based baseband processing architecture
