Interference from other users or from other base stations are limiting cellular IoT coverage.


The latest cellular enhancements for the so called cellular Internet of Things (IoT) defined by 3GPP [1] include EC-GSM-IoT, NB-IoT, and eMTC. In particular the 2G based EC-GSM-IoT standard is promising when in comes to instant deployment scenarios, since the base stations simply need a software upgrade. The mobile station, however, requires a redesign. The latter is not only due to changes in the standard procedures but also due to new and more stringed performance requirements when operating in a heavily loaded dense cell setup, where the interference created by other users or by other base stations becomes the most dominant performance limiting factor.

Project Description

The goal of this project is to study existing algorithms from the literature for single antenna interference cancellation (SAIC) and apply them to the operating regions for the cellular IoT in a Matlab simulation environment. If needed new algorithms have to be designed to meed the challenging interference suppression requirements defined by 3GPP [1]. The most promising algorithmic candidate will be implemented in hardware, either in VHDL or with HLS approach, and gets integrated into an existing modem structure. Then, the performance can be tested on an FPGA-based testbed using the evalEDGE platform and state-of-the-art signal generators to give the final performance prove. If required, it is also possible to do an ASIC project.
