Abstract—The Long Term Evolution Advanced (LTE-A) is an evolution of LTE. Its standardization had been done in 2011 and commercial usage was expected to commence in 2013. The technology was adopted faster by many developed countries throughout the globe. Unfortunately, the penetration of this technology into developing countries like Indonesia was very slow. In Indonesia, the number of mobile internet users was increasing dramatically. Current established 3G networks was predicted to be unable to handle users’ demand for years to come. Migration to the newer technology such as LTE-A has became a consideration for majority of mobile carriers in Indonesia although they have to implement new infrastructure to support the migration.

The aim of this project is to research and develop solution for low cost LTE-A femto base-station in Indonesia. The first phase of the development is to create calculations, models, and simulations in MATLAB then implement them in a Altera Stratix IV GX FPGA and Texas Instruments TMS320C6670 DSP. The design implementation in FPGA and DSP gives the developer rapid-prototyping before chip implementation takes place. With the help of signal generator and spectrum analyzer, the implementation is tested to make sure its compatibility and performance to LTE-A standards.
