Signal Reception and Recovery

Use the LTE Toolbox™ to create a frame worth of data, pass it through a fading channel and perform channel estimation and equalization. Two figures are created illustrating the received and equalized frame.

Fully synchronize, demodulate and decode a live eNodeB signal by using LTE Toolbox™ software. Before the user equipment (UE) can communicate with the network, it must perform cell search and selection procedures, and then obtain initial system information. This process involves acquiring slot and frame synchronization, determining the cell identity and decoding the MIB and system information blocks (SIBs). This example demonstrates this process and decodes the MIB and SIB1, the first of the system information blocks. Decoding the MIB and SIB1 requires a comprehensive that is capable of demodulating and decoding the majority of the downlink channels and signals.

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.

Capture and decode an LTE signal obtained either from a file or from radio by using LTE Toolbox™ software and various hardware support packages (HSPs). Before the user equipment (UE) can communicate with the network, it must perform cell search and selection procedures, and then obtain initial system information. This process involves acquiring slot and frame synchronization, determining the cell identity, and decoding the MIB and system information blocks (SIBs). This example launches a graphical user interface (GUI), which enables you to:

How LTE Toolbox™ can be used to detect the presence of UEs associated with an eNodeB. This is achieved by searching a downlink signal for DCI messages and establishing the set of unique identifiers (C-RNTIs) in use.
