To Plot the PAPR, use the following Matlab Code:-
first calculate the PAPR as follows
PAPR=10*log10(max(abs(d_ifft).^2) / mean(abs(d_ifft).^2));
then you can plot it as follows:
slice=200;
figure;
[N,X] = hist(PAPR, slice);
semilogy(X,1-cumsum(N)/max(cumsum(N)),'k');
good luck
I was sure you will answer my question. Therefore, I await your answer. Thank you very much. You are always solve my problems. Today, the answer was very good, especially when you tweaked me. This made me find out many mistakes, and I thank you very much.
In fact, I am really started self...
Hello Friends,
Kindly, I am writing a code for FIFO - RAM to use it with my UART controller. Now I got the code for the first part which is the FIFO + RAM. In fact it is not my code, I found it on the net which is as follows:
library IEEE;
library work;
use IEEE.std_logic_1164.all;
use...
Hi friends,
I am designing a FIFO handler but I face an error message in the If statement. Part of my code is:
library ieee;
use ieee.std_logic_1164.all;
-- FIFO Handler
Entity FIFO_Handler IS
Port(Rx_Ready : in std_logic;
Data : in std_logic_vector(7 downto 0);
Tx_Req : out...
Hello Friends
would somebody please help me to correct the error that i face. please see the attached picture.
I am using Quartus II Version 8.0, schematic design. when i compile the design I face the Error: Can't find name for bus. I am new on Quaetus. please help.
I would Like to thank you very much. I re-built the circuit and every think is working properly without errors.

thank you FvM very much. I re-built the circuit and every think is working properly without errors.
using SignalTap, I see that the Rx is always logic 1 and the Tx may change from logic 1 to logic 0.

Yes, I did this test and look what i got
Tx>Rx
00110101 >11111111
01001111 >11111111
but note what a funny results i got: using your test and still it connected to the...
as soon as I send any char from the pc to the FPGA, I receive 11111111 (or FF). I can not detect any thing on my pc from the FPGA when i try to send.
However, I used the VHDL code with the onboard rs232 and everything is fine.

I do double check for all the connections and...
i faced the same problem, I think it is better to try the MAX3232. I will buy tomorrow one MAX3232 and try again
thank you for your help

pin 2 = 7.5 volt
pin 6 = -7.5 volt
Note the supply now is 3v3 and the capacitors are 1 uF
but the same problem is appeared !!!
