Featured Examples
NB-IoT Downlink Waveform Generation
Generate LTE-Advanced Pro Release 13 narrowband IoT (NB-IoT) waveforms for test and measurement applications using LTE Toolbox™ software.
NB-IoT NPDSCH Block Error Rate Simulation
How LTE Toolbox™ can be used to create a NB-IoT Narrowband Physical Downlink Shared Channel (NPDSCH) Block Error Rate (BLER) simulation under frequency-selective fading and Additive White Gaussian Noise (AWGN) channel.
NB-IoT NTN NPDSCH Throughput
Demonstrates how to simulate a narrowband Internet of Things (NB-IoT) narrowband physical downlink shared channel (NPDSCH) throughput in a non-terrestrial network (NTN) channel. This example supports two narrowband NTN channels: the European Telecommunication Standards Institute (ETSI) Rician fading channel and the International Telecommunication Union Radiocommunication Sector (ITU-R) P.681 land mobile-satellite (LMS) channel.
NB-IoT Uplink Waveform Generation
Generate LTE-Advanced Pro Release 13 Narrowband IoT (NB-IoT) uplink waveforms consisting of the Narrowband Physical Uplink Shared Channel (NPUSCH) and the associated demodulation reference signals for test and measurement applications using LTE Toolbox™. Select from the NPUSCH reference measurement channels (RMC) for UE transmission testing, defined in TS 36.101 Annex A.2.4 [8], and the fixed reference channels (FRC) for base station receiver testing, defined in TS 36.104 Annexes A.14, A.15 and A.16 [9].
NB-IoT Downlink In-Band and Guardband Waveform Generation and Analysis
Generate a narrowband internet of things (NB-IoT) downlink waveform for in-band and guardband operation modes on an LTE carrier by using the LTE Toolbox™. The example also shows an analysis of the quality of the recovered NB-IoT physical downlink shared channel (NPDSCH) through error vector magnitude (EVM) measurements.
NB-IoT NPUSCH Block Error Rate Simulation
Create an NB-IoT Narrowband Physical Uplink Shared Channel (NPUSCH) Block Error Rate (BLER) simulation in frequency-selective fading and Additive White Gaussian Noise (AWGN) using LTE Toolbox™.
NB-IoT PRACH Waveform Generation
Generate LTE-Advanced Pro Release 15 narrowband internet of things (NB-IoT) waveforms consisting of the narrowband physical random access channel (NPRACH) for frame structure type 1 by using LTE Toolbox™.
NB-IoT Cell Search and MIB Recovery
How the LTE Toolbox™ can be used to fully synchronize, demodulate and decode a live narrowband internet of things (NB-IoT) downlink signal. Before the user equipment (UE) can communicate with the network, it must perform cell search and selection procedures and obtain initial system information. This involves acquiring slot and frame synchronization, finding out the cell identity and decoding the MIB. This example demonstrates this process and decodes the MIB. To decode MIB a comprehensive receiver is required, capable of demodulating and decoding the downlink channels and signals.
NB-IoT PRACH Detection and False Alarm Conformance Test
Implements the narrowband physical random access channel (NPRACH) missed detection and false alarm conformance tests for frame structure type 1, as defined in TS 36.141. You can measure the probability of correct detection of the NPRACH preamble in the presence of a preamble signal or switch the NPRACH transmission off to measure the false alarm probability.
