Receiver Preamp

Input signal, specified as a complex-valued matrix.

The size of the first dimension of the input matrix can vary to simulate a changing signal length. A size change can occur, for example, in the case of a pulse waveform with variable pulse repetition frequency.

Data Types: double

Enable enabling signal, specified as a column vector whose length equals the number of rows in the input signal X. Every element of TR that equals 0 or false indicates that the receiver is turned off, and no input signal passes through the receiver. Every element of TR that is nonzero or true indicates that the receiver is turned on, and the input signal passes through.

Dependencies

To enable this port, select the Enable enabling signal input check box.

Data Types: double | Boolean

Phase noise for each input sample of X, specified as a column vector whose length equals the number of rows in X.

The size of the first dimension of the input matrix can vary to simulate a changing signal length. A size change can occur, for example, in the case of a pulse waveform with variable pulse repetition frequency.

Dependencies

To enable this port, select the Enable phase noise input check box.

Data Types: double

Output signal, returned as a complex-valued matrix.

Data Types: double

Specify a scalar containing the gain in dB of the receiver preamplifier.

Specify a scalar containing the loss factor in dB of the receiver preamplifier.

Specify the receiver noise as Noise power or Noise temperature.

Specify a scalar containing the noise power in watts at the receiver preamplifier. If the receiver has multiple channels or sensors, the noise bandwidth applies to each channel or sensor.

Dependencies

This parameter appears only when you set Noise specification method to Noise power.

Specify a scalar containing the noise figure of the receiver preamplifier. Units are in dB. If the receiver has multiple channels or sensors, the noise figure applies to each channel or sensor. This parameter appears only when you set Noise specification method to Noise temperature.

Dependencies

This parameter appears only when you set Noise specification method to Noise temperature.

A scalar containing the reference temperature in degrees kelvin of the receiver preamplifier. If the receiver has multiple channels or sensors, the reference temperature applies to each channel or sensor.

Dependencies

This parameter appears only when you set Noise specification method to Noise temperature.

Select this check box to inherit the sample rate from upstream blocks. Otherwise, specify the sample rate using the Sample rate parameter.

Dependencies

This parameter appears only when you set Noise specification method to Noise temperature.

Specify the signal sampling rate as a positive scalar. Units are in Hz.

Dependencies

To enable this parameter, clear the Inherit sample rate check box.

Data Types: double

Select this check box to allow input of the receiver-enabling signal via the input port TR. T

Dependencies

This parameter appears only when you set Noise specification method to Noise temperature.

Select this check box to allow input of phase noise for each incoming sample using the input port Ph. You can use this information to emulate coherent-on-receive systems.

Dependencies

This parameter appears only when you set Noise specification method to Noise temperature.

Block simulation, specified as Interpreted Execution or Code Generation. If you want your block to use the MATLAB^® interpreter, choose Interpreted Execution. If you want your block to run as compiled code, choose Code Generation. Compiled code requires time to compile but usually runs faster.

Interpreted execution is useful when you are developing and tuning a model. The block runs the underlying System object™ in MATLAB. You can change and execute your model quickly. When you are satisfied with your results, you can then run the block using Code Generation. Long simulations run faster with generated code than in interpreted execution. You can run repeated executions without recompiling, but if you change any block parameters, then the block automatically recompiles before execution.

This table shows how the Simulate using parameter affects the overall simulation behavior.

When the Simulink^® model is in Accelerator mode, the block mode specified using Simulate using overrides the simulation mode.
