The best to think about bandwidth is Water flowing through the Pipe. If pipe's diameter is small then at at any given time from one end to another there is less water flowing through it. Even if you have larger bucket of water to pass through the pipe you can only pass at the full capacity of...
Hi eesha,
Thanks for your reply about viterbi decoding on the edaboad.com.
I wonder if you know the answer of another issue I am facing w.r.t to theoretical Probabilty of Bit error equation in Text books.
I don't have Reference [2] which is

Hi Prank
Say you want to add gaussain on the following 10 bits of BPSK modulated data
ModulatedData= randint(1,10,[1 0]);
And Say EbNo= 4dB
this is how you can calculated Real and Img part of noise
EbNo_lin=10.^(EbNo/10); % Calculate Linear value of EbNo
No= 1/EbNo_lin; %Calculate Noise...
I have plotted the effect of Decoder depth using BPSK modulation for K=4 code as shown in the Figure Below. For hard/soft decision decoding.
EbNo > x-axis
BER > y-axis
Realistically speaking decoder depth of 5K is more then enough. And for hardware implementation it will require 8x(4x5) i.e...
Hello Fellows,
I am implementing Trellis in hardware and have Survior path matrix for decoding length 5K where K is constraint length = 7.
Can someone tell me how to implement Track Back part for the viterbi algorithm.
Appreciated,
