Split Line ================================================================================== Split Line
The module libraries commonly used in Simulink include the following.
(1) Sinks Module Library: Includes modules that display or write output back. Display displays the input value; output port or external output port of the subsystem, scope, Float scope display the signal generated by the simulation; stopsimulation stop emulation when input is not equal to zero Terminator the disconnected output port as the terminal; XY graph shows xy coordinate chart.
(2) source (Sources) Module library: includes modules that produce various signals. band-limited white noise for continuous systems, CHIRP signal produces a sweep signal, clock generation and display simulation time; constant generates a constant value; Digital clock generates simulation time at a specific sampling interval The ground will not connect the input port to ground and so on.
(3) continuous (continuous) module library: includes a linear function model. Includes a differential element (derivative), an integral element (integrator), a linear state space system Unit (STATE-SPACE), a linear transfer function unit (Transfer Fen), a delay element (Transport delay), Variable Transmission delay Unit (Variable Transport delay), specifying a 0-pole input function unit (zero-pole).
(4) Math Operations (Simulink math operations and fixedˉpoint blocket math) Module library: Contains commonly used mathematical function modules. Includes the input signal Absolute Value Unit (ABS), calculates a reset signal amplitude and/or phase unit (Complex to Magnitude-angle), calculates a reset signal real and imaginary unit (Complex to Real-imag) and other mathematical functions.
(5) Communication Module library (Comunications Blockset)
Source (Comm Sources): In this library, you can form random or pseudo-random signals, or you can read a file or simulate a voltage-controlled oscillator (VCO) to produce a non-random signal.
Bernoulli Random binary Generator module: A binary random number that produces a Bernoulli distribution.
Binary vector Noise Generator module: Produces a binary random vector that can control the number of "1".
Random-integer Generator module: Generates a random integer range within (0~m-1).
Poission Int Generator module: A random integer that produces a Ji leping distribution.
PN Sequence Generator module: Generates pseudo-random sequence.
Gaussian Noise Generator module: Generates discrete Gaussian white noise.
Rayleigh Noise Generator module: Generates Rayleigh-distributed noise.
Uniform Noise Generator module: produces uniform noise within a specific area.
Voltage-controlled Oscillator module: Implement voltage controlled oscillator.
Comm Sinks: This library provides modules for both the delivery and display of the communication system to make it easier to analyze.
Triggered write to file module: writes data to files at the rising edge of the input signal.
Enor Rate Calculation module: Calculates the error bit rate and the false sign ratio of the input signal.
Source Code Coding Module Library: The source code is divided into two basic steps: source code and source decoding. The source code uses a quantization method to convert a source signal into a digital signal. The sign of the resulting signal is a nonnegative integer within a finite range. Source decoding is to restore the original information from the source encoded signal.
Channel Module Library: Provides a variety of communication channel models, such as Gaussian white noise channel.
Error detection and validation (Enor Detection Correction) Module Library: Provides modules for analyzing input and output, such as the module for calculating the error rate.
Modulation demodulation (modulation) module: Digital modulation demodulation and analog modulation demodulation, subdivision can be divided into amplitude modulation, phase modulation and frequency modulation.
