Introduction
Cellular standards and networks have traditionally been optimized for the high throughput requirements of modern smartphones. Recently the Internet of Things (IoT) has emerged as a new application with vastly different requirements. Ericsson predicts, that there will be 15 billion smart devices with Internet connectivity. Potential applications include smart metering, tracking in logistics, environmental sensing, and smart buildings. Two new variants of LTE have been standardized to fulfill the 5G requirements for these devices: LTE Cat-M1 (eMTC) and NB-IoT. They both offer reduced cost and power consumption, as well as improved coverage, but Cat-M1 supports more features and has a higher maximum throughput. As part of our communication platform, we are currently developing a modem for the Cat-M1 standard.
Project Description
One of the most challenging parts of designing a Cat-M1 IoT modem is improving the coverage by 20 dB. For the so-called PBCH this is especially difficult, since it has not been changed from legacy LTE. While it is transmitted continuously, the data changes every 40 ms. One idea is combining the information of these repetitions, even though they contain changed data.
Your task would be to study these algorithms and finding a way to efficiently implement them in hardware.
