Thesis description

 

Background:

This thesis will take place in System-On.Chip (SoC) architecture group at Ericsson. The group is involved in designing ASICs/FPGAs for next generation 5G products. A major hurdle in making these ASICs is their high-power footprint. As a part of solution to this problem, a technique called Digital-Pre-Distortion (DPD), is commonly employed. However, for the upcoming products, it is expected that the DPD itself will consume a significant portion portion of overall chip power (30-60%), making the design infeasible.

 

Problem statement:

This thesis will attempt to reduce the power consumed by the DPD. The MS thesis students will first study the existing single stage learning model (based on Volterra-Series). They will then modify the model from single stage learning model to dual stage learning learning. Finally, they will implement the modifications in RTL and evaluate the power consumption.

 

Students:

.       2

 

Tasks:

·       Understand the DPD functionality by looking at the Matlab code (4 Weeks).

·       Implement the proposed modifications in Matlab (3 weeks).

·       Implement the algorithm in RTL (4 weeks).

·       Evaluate power (2 weeks).

.       Write thesis (3 weeks).

 

Skills needed:

·       VHDL, Matlab, Synopsys Design Compiler.

·       Knowledge about hardware architecture.

·       Master of science program student in Electronics, Electrical Engineering.

.       Knowledge in signal processing is appreciated.

 

Application

Applications should include a short motivation letter, a CV (in English) and a record of a transcript.

The position can only be offered to students currently enrolled in a university program (Master).
