rsgenpolycoeffs

Generator polynomial coefficients of Reed-Solomon code

Syntax

x = rsgenpolycoeffs(N,K)

[x,t] = rsgenpolycoeffs(___)

Description

x = rsgenpolycoeffs(N,K) returns the coefficients for the generator polynomial of an [N,K] Reed-Solomon code.

[x,t] = rsgenpolycoeffs(___) returns the error-correction capability of the code.

Examples

Generate Polynomial Coefficients for Reed-Solomon Code

Generate polynomial coefficients for a (15,11) Reed-Solomon code.

Generate the coefficients using rsgenpolycoeffs.

genpoly = rsgenpolycoeffs(15,11)

genpoly = 1×5 uint32 row vector

    1   13   12    8    7

Input Arguments

N — Codeword length

positive odd integer

Codeword length, specified as an integer of the form N = 2^M – 1, where M is in the range [3,16].

Example: Set N to 15 for M=4.

K — Message length

positive integer

Message length, specified as a positive integer.

Output Arguments

x — Generator polynomial coefficients

Galois field array | double-precision array

Generator polynomial coefficients, returned as a Galois field array or double-precision array. The output is identical to the output of rsgenpoly.

t — Error-correction capability

positive integer

Error-correction capability of the code, returned as a positive integer.

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

For C/C++ code generation, these usage notes and limitations apply:

All inputs must be constants. Expressions or variables are allowed if their values do not change.
