Communication Signal Processing (CSP)

Introduction

Requirements of wireless systems change steadily. Future systems must offer higher system capacity, higher data rates and smaller latency than current systems to enable the increasing diversity of services offered by different service providers. New network topologies and smart ubiquitous environments are needed to satisfy the requirements of future services. The implementation of these systems requires crosslayer designs and optimizations close to realization. Devices operating in future wireless networks must be reconfigurable and more flexible than current designs. To fulfill these requirements both joint system level and device level, and joint signal processing algorithm and architecture research are needed.

Goal

The Communication Signal Processing Group (CSP) implements the strategy of CWC in the area of signal processing and radio engineering research for wireless systems. The group’s research goals are to allow more efficient use of network devices, decrease the power/energy consumption of wireless devices and allow the development of smaller and lighter wireless devices as well as improve the understanding on fundamental limits of wireless systems. Application areas of CSP group’s research results are mainly cellular systems, sensor networks and smart wireless devices. Interests groups for the application areas include device manufacturers, operators and semiconductor vendors.

Focus areas

Group’s focus areas are information theoretic foundations and its impact on wireless system design, signal processing system and device level algorithms, implementation architectures and efficient implementations as well as radio engineering and channel modeling. Currently, future technologies under investigation include multiuser multiantenna technologies for relay based and mesh networks, sensor network and wide area network integration, efficient computation platforms, and implementation design processes.

Teams

Currently, CSP group consists of 5 teams each concentrating on their specific expertise areas

  • Algorithms and Architectures for Wireless Systems
  • Iterative Information Processing
  • Positioning and Mesh Networks
  • Radio Engineering
  • Robust Signal Processing
