在将信号输入到基于表的功率放大器上之前，请使用退缩来扩展信号。它还显示了如何检查信号输入到放大器的功率分布，并验证放大器的实际行为是否与规范匹配。附录列出了示例中使用的辅助功能。

使用自上而下的方法为类似Zigbee®的应用程序设计RF接收器。它验证了无损伤设计的BER，然后在添加减值模型后分析了BER性能。该示例使用RF预算分析仪应用程序对有助于噪声和非线性预算的要素进行排名。

Use the RF Blockset™ Circuit Envelope library to simulate noise and calculate noise power. Results are compared against theoretical calculations and a Communications Toolbox™ reference model.

使用RF BloveSet™电路包膜库在超杂型RF接收器中对热噪声进行建模，并测量其对通信系统噪声图（NF）和位错误率（BER）的影响。使用Friis方程计算的参数和RF噪声测试台的通信工具箱™参考模型用于验证结果。

Use the RF Blockset™ Circuit Envelope library to simulate the performance of a Low IF architecture with the following RF impairments: Component noise

This model uses PSK-modulated signals to show the effects of adjacent and co-channel interference on a transmitted signal. You can view the effect of adjacent channel interferer and co-channel interferer together or individually.

How the antenna mutual coupling affects the performance of an orthogonal space-time block code (OSTBC) transmission over a multiple-input multiple-output (MIMO) channel. The transmitter and receiver have two dipole antenna elements each. The BER vs. SNR curves are plotted under different correlation and coupling scenarios. To run this example, you need Antenna Toolbox™.

Characterize a power amplifier (PA) using measured input and output signals of an NXP Airfast PA. Optionally, you can use a hardware test setup including an NI PXI chassis with a vector signal transceiver (VST) to measure the signals at run time.

Use digital predistortion (DPD) in a transmitter to offset the effects of nonlinearities in a power amplifier. We use models of a power amplifier that were obtained using the Power Amplifier Characterization example to simulate two cases. In the first simulation, the RF transmitter sends two tones. In the second simulation, the RF transmitter sends a 5G-like OFDM waveform with 100 MHz bandwidth.

Use Communications Toolbox™ blocks to model thermal noise, phase noise, and nonlinearity impairments of an RF transceiver. The model measures the effects of the impairments on the bit error rate (BER) of a communications system.
