Signal Operations

Scrambling, puncturing, interlacing, conversion between bit and decimal, and delay management

Perform various bit operations and delay management on signals and blocks of data.

Functions

`bit2int`	Convert bits to integers
`int2bit`	Convert integers to bits
`hex2poly`	Convert hexadecimal character vector to binary coefficients
`oct2poly`	Convert octal number to binary coefficients
`alignsignals`	Align two signals by delaying earliest signal
`finddelay`	Estimate delay(s) between signals

`comm.Descrambler`	Descramble input signal
`comm.Scrambler`	Scramble input signal

Deinterlacer	Distribute elements of input vector alternately between two output vectors
Derepeat	Reduce sampling rate by averaging consecutive samples
Descrambler	Descramble input signal
Find Delay	Find delay between two signals
Interlacer	Alternately select elements from two input vectors to generate output vector
Puncture	Output elements that correspond to 1s in binary puncture vector
Scrambler	Scramble input signal
Bit to Integer Converter	Map vector of bits to corresponding vector of integers
Integer to Bit Converter	Map vector of integers to vector of bits

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®.
