LTE HDL Toolbox


LTE HDL Toolbox

Model LTE communications subsystems for FPGAs and ASICs


LTE HDL Toolbox™ provides sample-based algorithms in Simulink® blocks for design and implementation of LTE wireless communications subsystems on FPGAs and ASICs. Toolbox algorithms, gateways between frame-based and sample-based processing, and reference applications enable you to compose an LTE baseband communications subsystem in Simulink.

You can modify the reference applications for integration into your own design. HDL implementations of the toolbox algorithms are optimized for efficient resource usage and performance for prototyping or production deployment on FPGA and ASIC devices.

The toolbox algorithms are designed to generate readable, synthesizable code in VHDL® and Verilog® (with HDL Coder™). For over-the-air testing of LTE designs, you can connect transmitter and receiver models to radio devices (with Communications System Toolbox™ hardware support packages).


Reference Application Hardware Subsystems


LTE Cell Search, MIB, and SIB1 Recovery


Filtered OFDM (F-OFDM) Transmitter


Waveform spectrum from the example F-OFDM transmitter.

LTE and Wireless IP Blocks


LTE IP Blocks

Intellectual property (IP) blocks in LTE HDL Toolbox enable you to model and simulate efficient hardware implementations of LTE-specific algorithms, such as turbo, convolutional, and CRC encoders and decoders as well as OFDM demodulators. You can then use HDL Coder™ to generate synthesizable VHDL or Verilog RTL.


Multistandard IP Blocks



Verification Using Your LTE Golden Reference


Conversion Between Frames and Samples

Convert frame-based waveforms from MATLAB® and LTE Toolbox™ to a stream of samples with control signals for processing in hardware. Then convert the streaming hardware output to frames for verification against your golden reference algorithm.

Frame-to-sample conversion and control signal generation.
