reed solomon decoder vhdl

Hello!

Someone could give me points to download the rs_code? I really need it :-(

Thank you very much in advance

reed solomon best implementation source code

You need not points to download it. Just push on "free mirror" (or "download" as well as it costs 0 points )

Those who need exactly RS(255, 223) code in C could download it from
https://www.ka9q.net/code/fec/

koetter interpolation matlab

Hi,
I am trying to expand the program that I found here about encoder and decoder. I want to plot the ber vs snr. I tried with biterr function but I take as error this:

Function 'log' is not defined for values of class 'uint8'.
???Error in ==> log at 15
[varargout{1:nargout}] = builtin('log', varargin{:});
Error in ==> biterr at 190
sym_len = floor( log(tmp) / log(2) ) + 1;

Also an error in the case of AWGN, I suppose that and this caused from the same reason, because the output is in unit8 format, but if I change it the programm does not work properly.

??? Error using ==> plus
Integers can only be combined with integers of the same class, or scalar doubles.

Error in ==> RS_test_code at 15
cnoisy = data_enc + noise; % Add noise to the code.


Could you please help me?

ber after rs decoder matlab

Hi everyone;

I doing the RS (255, 191) now, and need implement it with the matlab code and VHDL code. Can any one upload the Reed solomon Code(matlab code or VHDL code with explantion) for encoder and decoder.

p/s: I also dun understood how to get D^8+D^4+D^3+D^2+1, hope u all can explain or upload any online ebook about this too.


Thanks yah...

Best regards,
shirley chee

Hello
these are MATLAB m-files.
These files is usefull for GF operation such as multiply and Add

how to create Non return zero level(NRZ-L) and non return zero mark (NRZ-M) waveforms using vhdl? i could not think the solution....can you give me the vhdl code at my email esa_screen@yahoo.com.sg I'm using Quartus II software. I really need help from everybody who knows it. Your help is really appreciate.

reed solomon source code for octave

hello
i m new to this forum
and i need Reed solomon matlab codes for encoder and decoder
can anyone email me on" kamran_haleem@yahoo.com".
or tell me how to earn points so that i can download that.

reed solomon codes source code in matlab

Hi,
If I use the fuction rsgenpoly in the Matlab,
r=rsgenpoly(255,239) to generate the polynomial for RS (255,239). I get return value as:r = GF(2^8) array. Primitive polynomial = D^8+D^4+D^3+D^2+1 (285 decimal) Array elements =
Columns 1 through 10
1 118 52 103 31 104 126 187 232 17
Columns 11 through 17
56 183 49 100 81 44 79
If I use a different tool to generate the polynomial , the tool is at the website of
**broken link removed**
I got the return value as:
G(x)=x^16+59x^15+13x^14+104x^13+189x^12+68x^11+209x^10+30x^9+8x^8
+163x^6+41x^5+229x^4+98x^3+50x^2+36x+59
Both method are use the same field generator as P(x)=x^8+x^4+x^3+x^2+1
Now My Question is:
1. why they come out two results and if both are equal
2. which set of value should be use to do the RS encoder.

please am new to reed solomon code. what does alpha stand for?

thank you,very very much much

I'm writing this program .but in DSP assembler for 21xx series .Is not hard to write in C . I can give you some insight if you need !

Hello Dears...

i'm new here...

understood everything, but whats this point.???

 

[rohithosho]

what are rs code?

can anyone explain me what BCH(32,24) or BCH(64,56) mean.. I am working on verilog code for this.. my mentor expects me to get the result as follows
(HEX)
MSG - 000F02
CODE - D0000F02

MSG - EDBA223FF40953
CODE-F5EDBA223FF40953

MSG - 66B2F9FCB671F2
CODE- 9966B2F9FCB671F2

Thanks in advance

encoder of reed-solomon codes

The BCH codes consists of code n=size and k=dimension CHN(n,k)
Your teacher request for ENCODING a word or message ..so he gives you a word and you should provide the enconded word or message .
Is easy to see in the given examples that the encoding is of type SYSTEMATIC
