Modeling Basics
Resource grids, resource extraction, FDD and TDD duplexing modes, parameter
structures
LTE Toolbox™ functions create valid 3GPP parameter sets and model LTE physical layer processing. The parameter configuration functions create and initialize parameter structures that align with specified 3GPP reference measurement channel (RMC), fixed reference channel (FRC), or E-UTRA test model (E-TM) settings. Use the parameter structures as inputs to waveform generation functions to create waveforms compliant with 3GPP LTE and UMTS standards.

. - Map Reference Signal to Resource Grid
This example shows how to map the cell specific reference signals to the resource grid for a subframe in the two antenna case. - Resource Grid Indexing
LTE Toolbox provides facilities to generate sequences of symbols corresponding to the physical channels and signals.
Duplexing
- FDD and TDD Duplexing
Describes frequency and time division duplexing (LTE frame structure type 1 and 2) and representation in the LTE Toolbox product.
Parameter Structures
- Parameterization
Describes the function parameter style, the way parameters are passed to the toolbox functions. Some of the functions in the LTE Toolbox require a large number of parameters. To simplify this process and to group together relevant parameters, structures are used. - LTE Parameterization for Waveform Generation and Simulation
This example shows how to parameterize end-to-end simulations and generate static waveforms by using LTE Toolbox™ software. - UL-SCH Parameterization
Describes parameterization forms for the UL-SCH and PUSCH related functions.
