PBCH/MIB Repetitions. Image source: [2].


LTE Cat-M1 (eMTC) is a 5G standard optimized for low energy consumption and excellent coverage. We're currently developing a modem for the Cat-M1 standard. 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 [1].

Project Description

The current proposal corresponds to a brute-force approach to combining this information. As a first step in your project, you will study ways to reduce the complexity on an algorithmic level. Based on this, you will come up with an efficient architecture to implement this algorithm. You can either design an ASIC with only this block, or integrate it into our RF SoC and test it on an FPGA.
