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 needs a software upgrade. The mobile station, however, requires a redesign. The latter is not only due to changes in the protocol 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.

To accommodate the expected needs of the cellular Internet of Things (cIoT), the 3GPP has standardized Extended Coverage GSM for the Internet of Things (EC-GSM-IoT) as an extension to the 2G standard. It aims to offer extended coverage, lower energy consumption and support for a vast number of devices.

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 meet the challenging interference suppression requirements defined by 3GPP [1].

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

Short Description

To accommodate the expected needs of the cellular Internet of Things (cIoT), the 3GPP has standardized Extended Coverage GSM for the Internet of Things (EC-GSM-IoT) as an extension to the 2G standard. It aims to offer extended coverage, lower energy consumption and support for a vast number of devices. Meeting the interference requirements of this standard presents a challenge, for which no solution has been published yet.

In this project the tasks of Adjacent Channel Interference (ACI) and Co-Channel Interference (CCI) suppression and detection are presented and analyzed. Algorithms for ACI have been evaluated. The presented solution is able to surpass the EC-GSM-IoT requirements for all coverage classes (CCs) by at least 1 dB.
