Hye,
Actually, I'm also doing the research about the "Recognization of medical image using significant DCT coefficients quantization". Here, i just want to know how set the compression tolerent range for significant DCT coefficients? I need help and hope you all can give me some idea. I...
Hye,
i just want to know how set the compression tolerent range for significant DCT coefficients using matlab? I need your help or consideration if you are busy or not to burden you, if you can give me some idea. I really need your idea and suggestion. Really hope the feedback from you...
hi everybody
I'm trying to implement MEDICAL IMAGE BASED ON DCT using Matlab.
Can anybody provide me with the information about coding.I have already done this coding..but i don't know how to apply statistical analysis in this project.hope anybody can help me.
thanks!

Im having problem with my counter which will control my storage data in ROM to multiply with another ROM. Both rom will stored matrix data. im having a problem with my counter where it only can count from 0 to 15. For my design i need a counter that need to count from 0 - 3 and repeat counting...
eye diagram qpsk
GaoMing;
I already read about 1st Nyquist ISI criterion..but..i still didn't understand why scatter plot change to distribute after we put the RRC filter.
i also didn't understand why the amplitude of the waveform I, Q and QPSK modulator decreasing after put the RRC filter...
raised cosine qpsk
thanks GaoMing for ur clearification about this matter. From what u have post here i will try to understand and learn more in detail regarding this things. But i might need some more help from u. I hope u can help me. Thanks for ur all time helping.. : )
using matlab to plot a qpsk modulator
owh..i see...tq GaoMing....:D
if u dont mind i would like to ask u come question. hopefuly u can help me... :)
1) what is the function of the real-imaginary to complex and complex to Real-imaginary in this operation.
2) why there is some noise at the...

square-root nyquist using simulink
Hi, i try to implement a QPSK modulator using simulink. This is a expected result of the modulator where im using a QPSK block in library.
As for my own build here is the model of the QPSK block. But there is an error at Root Raised Cosine Filter block. Is...
dear radix,
thx for ur answer here. i have tried both method and its work perfectly fine. My input is guarante to be "one-hot so i`ll just use the fist code. Btw i have learn a another ways to convert S-P from 2nd code tho.. Thank You Radix!!! :D
can someone help me to correct this?
i just want to change the input (4bit) into a single bit in a 4 different port (O1,O2,O3,O4).
library ieee;
use ieee.std_logic_1164.all;
entity encoder is
port( I: in std_logic_vector(3 downto 0);
O1: out std_logic;
O2: out std_logic;
O3...
i have modify this code from my previous project. For the component i just copy from module that i alrdy done.
lol thx for that 1.. i have change for component mul but still got error..
its said that : Error: Node instance "stage4" instantiates undefined entity "mul"
component mul
