dear friends
this is a document about SPECTRUM SENSING ON LTE FEMTOCELLS FOR GSM SPECTRUM RE-FARMING USING XILINX FPGAs
ABSTRACT
Femtocells are a promising solution to provide high coverage
and high data rates inside consumer’s homes while cutting operator
costs significantly. Next generation Long Term Evolution
(LTE) femtocells are likely to be deployed in GSM spectrum,
increasing frequency utilisation and allowing a smooth
transition to LTE. This paper proposes to use a spectrum sensing
technique specialised for LTE signals to avoid interference
between neighbour femtocells without operator intervention.
Simulation results of the detection characteristics
are given. A demonstrator has been implemented on a Xilinx
ML507 Virtex 5 prototyping board, using our flexible FPGAbased
cognitive radio framework, which allows to use runtime
reconfiguration of the FPGA to switch between sensing
and normal operation. It demonstrates the sensing algorithm
on a real platform.
