ineed matlab code.

a$)$ What is the constraint length of this encoder?What is the

generator polynomial in octal form?

b$)$

c$)$ Write a MATLAB program to find the output of the convolutional

encoder $($coded vector$)$ when the input sequence message is

$1001110011000011100101100101001110110011.$

d$)$ If the channel is AWGN with $\frac{S}{N}$ of $5dB$ and $0dB$ at the receiver,

what will be the decoded message if we use a Viterbi decoder?

What will the bit error rate? $($Notice the input data is very short!$).$

To find the bit error rate it is better to generate a random binary

message of hundreds of thousands of bits.

e$)$ Instead of Convolutional coding, use a block code $(15,5).$ Repeat

parts $($b$)$ and $($c$)$

f$)$ Compare between the convolutional and block codes in terms of

the decoded message.

Hint. Useful MATLAB functions that can be used:

encode.m$,$ randi.m$,$ convenc.m$,$ vitdec.m$,$ poly$2$trellis.m$,$ awn.m$,$

decode.m$,$ biterr.m

Write a PDF short report describing your findings. The report should

include a detailed description of your results. The listing of the function

you wrote must be included with the necessary plots. Don't forget to

comment on the results you obtained.
