rsencof - Encode ASCII file using Reed-Solomon code

Syntax

rsencof(file_in,file_out); rsencof(file_in,file_out,err_cor);

Description

rsencof(file_in,file_out) encodes the ASCII file file_in using (127, 117) Reed-Solomon code. The error-correction capability of this code is 5 for each block of 127 codeword characters. This function writes the encoded text to the file file_out. Both file_in and file_out are string variables.

rsencof(file_in,file_out,err_cor) is the same as the first syntax, except that err_cor specifies the error-correction capability for each block of 127 codeword characters. The message length is 127 - 2 * err_cor.

Note If the number of characters in file_in is not an integer multiple of 127 - 2 * err_cor, the function appends char(4) symbols to file_out.

Examples

The file matlabroot/toolbox/comm/comm/oct2dec.m contains text help for the oct2dec function in this toolbox. The commands below encode the file using rsencof and then decode it using rsdecof.

file_in = [matlabroot '/toolbox/comm/comm/oct2dec.m'];
file_out = 'encodedfile'; % Or use another filename
rsencof(file_in,file_out) % Encode the file.

file_in = file_out;
file_out = 'decodedfile'; % Or use another filename
rsdecof(file_in,file_out) % Decode the file.

To see the original file and the decoded file in the MATLAB workspace, use the commands below (or similar ones if you modified the filenames above).

type oct2dec.m
type decodedfile
