Help Needed on Matlab Code to Generate Orthogonal Codes
I am new to matlab but I need code urgently to pass my final year project. The project intends to compare Walsh-Hadamard and Gold codes. The matlab code should do the following: ---------------- PART ONE: ---------------- (1) generate random message bits (2) generate walsh-hadamard codes (3) modulate the signal (4) transmit the spreaded signal (5) plot the message and walsh-hadamard codes as rectangular pulses; also plot the spreaded signal, with labels on plots. (6) on the same figure, do the reverse, i.e plot the demodulated, de-spreaded signal, just as it was shown at the transmitter side....

Matlab code to C-code generation using emlc
Hi, I am trying to convert my matlab code to C-code using the emlc command (of embedded matlab). Upon execution,I realize the following problems- 1. Many .c and header files are generated, how to compile them is an issue for me... 2. A lot of header files are not found when I try to compile the files using Dev-Cpp 3. No main function is generated resulting in the error- invalid reference to win32@16 Kindly help. Thanks a lot in advance. -Pradyot ...

Precise signal generation using matlab
Can I generate a signal using MATLAB which is in the order of microseconds( Stays low for 1microsecond and becomes high the next microsecond) and output the same via serial or parallel port?

I personally wouldn't count on it, though. You _might_ be able to do an acceptable job of timing a signal if you manage to find an appropria...

signal construction using fourier series coeffiecients
Hello i made this code to produce the fourrier series coefficients and am trying to recostruct the signal V = 5; k = -10:10; m=1; Ck = zeros(size(k)); X = zeros(size(k)); t=-4:.01:4; for m = 1:length(k) if mod(k(m),2)~=0 Ck(m) = (1./(j*k(m)*pi) .* cos((2*k(m)*pi)/3) - cos((k(m)*pi)/3)); for z = 1:length(k) X(z) = Ck(m).*exp(j*k(z).* (pi/3).*t); end end end Ck(m) as i checked it works just fine am getting the coefficients but i cannot reconstruct the signal , i am getting this err...

C Code generation using Embedded MATLAB
Hi, Is there any workarounds to generate C-code using Embedded MATLAB for variables whose size is know only at run-time and hence memory allocated dynamically. A simple case would be to generate the code to determine the median of a certain number of points, the number of points being known only at run-time. To avoid dynamic memory allocation, suppose I use a worst case size scenario of 4096 data points, the code generated by Embedded MATLAB is specific to this size. I cannot use this generated code to determine the median of, say 4095 points, because the way median is determined is different...
