I have programmed Atmel microcontrollers in the past using In-System programming in conjuction with my laptops serial port. If you do a search on the internet you will find many usefull documents!

Re: Help QPSK
MATLAB provides an excellent Help, just do a search there and most of your answers will be there!
len = 10000; % Number of symbols
M = 4; % Size of alphabet
msg = randint(len,1,M); % Original signal
% Modulate using PSK
txpsk = pskmod(msg,M);
nsamp = 11; % Oversampling rate

I am not an expert in sound processing ,however the way I think of this problem is that a pure sound signal is a real signal however because in reality when this signals reaches our 'ears' it is disturbed by other signals. The different signals that disturb the original sound wave is impossible...
how is sound waves related to complex numbers
Hi there,
Could you please tell me when a sound signal is complex valued. If possible please provide references.
Thanks,
mileoung
sometimes this symbol is used to represent the low-pass equivalent kernels related to baseband Volterra models

Re: linearization techniques
The best reference so far on Volterra series is:
The Volterra and Wiener Theories ofNonlinear Systems
M Schetzen - Ed. John Wiley & Sons, 1980
A novel technique on PA predistortion is discussed in
A new Volterra predistorter based on the indirect...
Re: pls help me in matlab..
what eecs4ever is saying translates into MATLAB code as
% Generate 50 uniformly distributed random samples
Xunif = rand(1,50); % 50 samples of a uniform dist
% with fX(x) = {1 when 0<=X<=1 and 0 otherwise}
% Define the desired means and variances

Re: REGARDNG OFDM ( NO OF CHANNELS, SERIAL TO PARALLEL CONVE
The way the conversion is done in OFDM is by making use of a IDFT (Inverse Discrete Fourier Tranform) block at the tranmiter to sum all the different carriers into one and the other way round for the receiver (i.e. DFT)
cocktail party problem bss
All the discussion taking place here is about a mixture of linear processes....could someone tell me if there is any way to get arround the problem of blind source separation of volterra outputs with the use of Higher Order Statistics only.
matlab adsl
A script with a strip down version of a DMT Adsl system.
Description: The following is a simulation of the DMT system, similar to implementation as done in ADSL systems. The bandwidth has been divided into 32 sub-channels of equal width. Each sub-channel has been allocated bits...
According to Brillinger's Book (Time Series: Data analysis & Theory, p.95), the IFFT (Inverser Fourier Transform) output in OFDM systems, is approximately white gaussian when the input is zero mean IID.
Could some upload the proof for this statement.
Thanks for your help-time,
mileoung
Re: motion control
there are plenty of ICs that can be used to drive a servomotor....all you need is a few dataline signal and a few digital gates, thats it. Do a search on the internet or RS components.
