A Novel Narrowband Internet Of Things NPUSCH Format 2 Receiver
2019 27th Signal Processing and Communications Applications Conference (SIU), 2019In this study, we propose a new Narrowband IoT (NB-IoT) receiver design for NPUSCH Format 2, which is equivalent to the Minimum Mean Square Error (MMSE) receiver mathematically. The proposed design changes the scrambling operation, and replaces the hard decoding of BPSK modulation symbols with soft decision decoding.

A Simple and Efficient Link Adaptation Method for Narrowband Internet of Things
2019 IEEE 21st International Conference on High Performance Computing and Communications; IEEE 17th International Conference on Smart City; IEEE 5th International Conference on Data Science and Systems (HPCC/SmartCity/DSS), 2019This paper proposes a simple and efficient link adaptation method for Narrowband Internet of Things (NB-IOT). The proposed method will perform link adaptation from two dimensions. First, the combination of the modulation and coding scheme (MCS) level and the resource unit (RU) number can select a larger transport block according to the packet size ...
