Design and implement sample rate conversion for an LTE receiver front end. The model is compatible with the Wireless HDL Toolbox™ receiver reference applications, and supports HDL code generation with HDL Coder™.

Filtered OFDM (F-OFDM) applies a filter to the symbols after the IFFT in the transmitter to improve bandwidth while maintaining the orthogonality of the complex symbols. This example implements a transmitter F-OFDM for HDL code generation. The example shows how to go from a MATLAB® reference model to an HDL-optimized Simulink® model. It includes converting from double to fixed-point types, and minimizing the resource use of the design on an FPGA.

Implement a variable-size FFT using a single FFT core.

The workflow to measure the BER of the Wireless HDL Toolbox™ Turbo Decoder using parsim to parallelize the simulations across EbNo points. This approach can be used to accelerate other Monte Carlo simulations.

The implementation of an additive white Gaussian noise (AWGN) generator that is optimized for HDL code generation and hardware implementation. The hardware implementation of AWGN accelerates the performance evaluation of wireless communication systems using an AWGN channel. In this example, the Simulink® model accepts signal-to-noise ratio (SNR) values as inputs and generates Gaussian random noise along with valid signal. The example supports SNR input ranges from –20 to 31 dB in steps of 0.1 dB.

The implementation of a digital predistorter (DPD) model that is optimized for HDL code generation and hardware implementation. The predistortion mechanism is executed in two stages. In the first stage, a set of DPD coefficients are estimated based on the input and output data of the power amplifier (PA). In the second stage, the input data of the PA is predistorted based on the estimated DPD coefficients and provided as new input to the PA. This example demonstrates a system-level simulation in which the DigitalPredistorter subsystem generates HDL code, while the DPD coefficient estimation generates C/C++ code. This example model supports only Normal and Accelerator simulation modes.
