Digital Radio Algorithms & Signal Processing Developer

Job Description

Date: Oct 3, 2019

Job Summary

 

Have you ever wondered who is crafting plans for 5G and making sure that there is a cellular network that enables considerable higher data speed (up to 100 Gbit/s)?  Yes?  Then you have come to the right place!

 

When you press the button on your wireless device asking for upload/download service there is a cellular base station that processes all that data in real-time and updates a large number of parameters in a fraction of second to enable fast data to transfer. If you are interested to work with us and enable this future, you should continue reading.

 

Ericsson is a world leader in the rapidly changing environment of communications technology – providing equipment, software and services to enable transformation through mobility.

Headquartered in Stockholm – Sweden, Ericsson is a publicly listed company with more than 100,000 employees.

 

More than 180 countries use Ericsson equipment, and more than 40 percent of the world's mobile traffic passes through Ericsson networks. Technology is at the heart of our business. Ericsson engineers, researchers and scientists around the world are working on what’s next in information, communications, and telecommunications (ICT).

 

The Digital Radio Algorithms Design section is responsible for the development Digital Radio Algorithms for new radio hardware units, a part of Ericsson's 2G, 3G, 4G and 5G base stations. We develop antenna near signal-processing firmware for radio signal enhancement. The teams are highly skilled with very good knowledge in both our own parts of the radio as well as the overall Radio Unit (RU) products.

 

Our teams are involved in all phases of technology development from research and technical studies, to pre‐development, product development and advanced TR handling.

 

Antenna near signal processing blocks should be investigated, developed, and implemented in ASICs, FPGAs and/or structured ASICs.

Daily work could consist of designing signal processing algorithms for Linearization, Clipping, Filtering, Automatic Gain Control, Cancellation, Impairment Correction and Antenna Calibration. It can include design and implementation of interfaces, radio modelling, synchronization, scheduling logic but also advanced trouble shooting and customer support.

 

We work with both HW and SW and provide connection between those with supervision and control.

Together with our team, you will be responsible for delivering parts of the digital radio on‐chip design that is the heart of our Ericsson Radio units.
