Digital Radio Algorithm Design Engineer

The Digital Radio consist of Algorithms / Functions and Implementation and are responsible for development of new radio hardware units, a part of Ericsson's 2G, 3G,4G and 5G base stations. The main focus area is on developing firmware for Algorithm development (like Linearization and CFR (Crest Factor Reduction)), algorithm control and functions in MCUs (Micro Controllers); internally called Device Processors (DP). 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 several areas like research, technical studies, 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 and implementing linearization algorithms for efficiency enhancement solutions for RF amplifiers, design and implementation of interfaces, synchronization, and 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 part of the digital radio on-chip design that is the heart of our Ericsson Radio units.
