hi i am in great need of matlab program to generate 1)ASK 2)FSK 3)qpsk WAVEFORMS please help me out.
Hi everyone I'm new here and I need some help from u. I have to make a matlab program in order to draw the IQ diagram for some signals as BPSK and qpsk. I have to correct the Doppler effect and the phase shift with PLLs. I think Costas loops are good for correcting the phase shift. But what about the Doppler effect ? What have I to (...)

Hi Folks I am building OFDM in simulink (qpsk with 2048 carriers) and i would like to add the turbo codes to it as FEC. I download the turbo code from and I add it to my OFDM design so I have these questions: is that acceptable? and what about my sample t
respected sir, can u give me coding for qpsk in matlab????
sorry for my late reply........ i tried to start to implement the energy detection technique with a simple code using qpsk but there was a different between the simulated curve and the theoretical curve ........ i designed the code based on constant false alarm rate , please help me in finding the problem in the code here is the code : clear all
hello, Hey friends.. I need matlab code for digital modulation techniques... like ASK, PSK, BPSK, DPSK, QAM, qpsk, etc... If you have that, Please post that... Advance tnxs to you
hi... i have something to ask everyone...if i want to design an OFDM transmitter for UWB application,so i need 128 point IFFT. For IFFT,100 points are for data ,the rest are for guard interval and cyclic prefix. that means we need 100 qpsk signals to pump out as IFFT's input data , is it true?
For qpsk constellation, decision boundary is +-45 degree, which is different from the phase error. For analysis of phase error on the performance of QAM, the phase noise could be modeled as Gaussian noise. Then you need evaluate the conditional error probablity due to the phase noise. It is more compilcated if the magnitude imbalance is also consid
i want to changed N(to 96) but i can't. can someone help me on that please? it is very urgent thank you. this is the qpsk program(i found on the internet): clear; fcarr=5e3; % Carrier frequency(Hz) N=8; % Number of data bits(bit rate) fs=20*1e3; % Sampling frequency Fn=fs/2; % Nyquist frequenc
here is i have a matlab code as follow : --------------------------------------------------------------------------------------------- clear N = 10^6; % number of bits or symbols Eb_N0_dB = ; % multiple Eb/N0 values K = 4; for ii = 1:length(Eb_N0_dB) % Transmitter ip = rand(1,N)>0.5; % generating 0,1 with equal proba

Hello I just completed a assignment for qpsk in matlab, it works fine, but wanted to see if I could get some help on run time as it takes a while to execute the m file. Any pointers would be appreciated. I am only simulating the baseband part. Thanks in advance for any suggestions! In the block diagram i forgot to label x (inphase) and y(qua
hi can any one tell me the program for BPSK qpsk and is there anything that can be done on matlab for pi/4 qpsk
1. For P2P microwave link, first you should know what type the signal is: FSK/qpsk/16QAM/64QAM/128QAM/256QAM/CDMA..., 56M/28M/14M/7M/3.5M etc. And estimate the receiver signal level by link budget. 2. Abouthow to program it, you can refer Microwave Office Examples, there are many examples about 128QAM/16QAM BER calculate. BER has some relation w
Hello everyone, I've been trying to simulate a Rayleigh channel in matlab and have stumbled upon a difficulty. Originaly i was given a simulation that calculates the BER of an AWGN channel in qpsk, and was asked to change it to a Rayleigh fading channel. The Original program is as such: (...)
Hi dear Yes I downloaded the fft core on the FPGA , it was in a system consisting of a randomizer , convolutional encoder , RS encoder , qpsk mapping and FFT, the kit was connected to the PC through serial port. Using a program to send data serially to the FPGA ( which is considered my transmitter ) then take the data serially back leaving the
