Digital Pre-Distortion for Concurrent Multiband and Multiple Antenna Transmission

The proposed project aims at the design and implementation of low complexity digital pre-distortion (DPD) algorithms for concurrent multiband wireless transmitters. The power amplifier (PA) is one of the major sources of power dissipation in wireless base stations. The DPD techniques enable the PA to operate in higher power levels where it has its highest efficiency. To address the ever increasing demand for higher data rates, the carrier aggregation techniques are being adopted by the current and upcoming wireless standards. The requirement for concurrent transmission over multiple bands in carrier aggregation schemes poses a great challenge to the design of feasible DPD algorithms. The multiband DPD algorithms currently available in the literature are computationally too complex to be implemented in practice. TEKTELIC believes that the proposed research project will result in low complexity and yet effective DPD designs that can be used in the company’s future multiband radio products.
