Abstract

In the transmission from the outdoor environment to indoor, the radio wave is severely attenuated due to the complex indoor environment, which insidiously restricts many applications. The concept of femtocell is proposed to overcome the signal attenuation problem for indoor services. In this paper, we show the baseband design and software-defined radio implementation for Long Term Evolution (LTE) femtocell. We design a universal baseband architecture and efficient signal processing procedure, and adopt powerful multicore digital signal processors (DSPs) to execute these signal processing programs. Our implemented LTE femtocell exhibits a real-time communication ability, which is well verified by some testing procedure described in the paper.
