This paper presents the FPGA design of an interference-aware digital front end tailored for heterogeneous multi-cell LTE-based systems. A resource-optimized RTL architecture has been implemented and validated under realistic operating conditions using the GEDOMIS® testbed. The parallelization and concurrent resource utilization of the joint synchronization and interference detection processing blocks is covered with low-level details.
