Postdoc in Algorithms and Architectures for Coherent Optical Communication

Linköping University
Country of Position:

Subject Area: 
Signal Processing for Communications and Networking
Start Date: 
21 October 2020
Expiration Date: 
27 November 2020
Position Description: 

Postdoc in Computer Engineering formally based at the Department of Electrical Engineering

In the Division of Computer Engineering we perform research about efficient processing architectures for, among others, coherent optical communication. With the very high data rates in fiber optical communication systems, the available oversampling is a limiting factor. One primary objective of this post-doc position is to work on efficient solutions for fractional oversampling receivers for coherent optical communication. Traditionally, the adaptive equalizers operates at an integer multiple of the symbol rate. We envision that this can be done at a fractional multiple instead, avoiding both the higher sample rates and sample rate conversions involved with the integer multiple scheme. However, this require new algorithms, which also must be efficiently implementable.

The position is funded by the ELLIIT strategic research environment, and it is expected that the successful candidate attends the annual workshops and presents the outcomes. There are collaborations with the Division of Communication Systems at the Department and with Chalmers University of Technology within the project.

A Postdoc will essentially carry out research. The position may also involve teaching, but during no more than a fifth of work time. The duties may also include, if deemed relevant, engaging in PhD supervision and contributing to PhD courses.

The applicant should have a strong background in digital signal processing, ideally for optical communication. In addition, the applicant should
have experience with hardware implementation of digital signal processing algorithms using HDL (VHDL and/or Verilog) and logic synthesis (FPGA and/or ASIC). Scholarly proficiency must have been demonstrated through original research resulting in publications in internationally recognized journals and conferences. The applicant should be able to work effectively both individually and together with other researchers.

Very good communication skills and very good knowledge of English, both verbal and written, are expected.

The position requires a doctorate or an equivalent degree from a foreign university. The doctorate shall have been obtained no longer than three years before the expiration date of the application and be in relevant fields of electrical or computer engineering.

Appointment time
A Postdoc is appointed until further notice, but for no longer than two years. The appointment can be renewed if there are special reasons.

Starting date 
By agreement.

The University applies individual salary scales adapted to the experience of the employee and to the labour market.
