Topics
- Find Delay for Encoded and Filtered Signal
Determine the delay for a convolutionally encoded and filtered link.
- Delays
Computing delays in multirate models and in models having multiple delays.
- Matrices, Vectors, and Scalars
Simulink® supports matrix signals, one-dimensional arrays, sample-based processing, and frame-based processing.
- Floating-Point and Fixed-Point Data Types
The inputs and outputs of the communications blocks support various data types.
- Fixed-Point Integer to Bit and Bit to Integer Conversion in Simulink
Use the Bit to Integer Converter (Simulink) and Integer to Bit Converter (Simulink) blocks in an example with fixed-point signals that performs audio scrambling and descrambling in Simulink®.
