hello frnds, I have a doubt about selecting random no generating capacity of matlab. Can any one suggest me using random no generator in order to randomly select an element from a the elements of the given array? for eg if the array is AR=[1,2, 3, 4 , 6] then the random number generator should be able to select any element from the AR randomly

hi, u can use 'rand' function in Matlab which gives the uniform random in the range (0,1). if u want Random numbers in (-1,1) use 2*rand(1,20)-1 so for (-100,100) 100*(2*rand(1,20)-1); hope it will helps u. if u aren't intrested to use 'rand' fun

Dear All, my project requires me to generate random samples which follow a Hyper- Erlang distribution. How can i do this in Matlab? In my case, the Hyper-Erlang distribution consists of weighted sum of 2 erlang distributions. (very much the same as hyper exponential distirbution, which is made up of weighted sum of exponentials) Matlab is able to generate random samples from some commo...

Hi, I am an Mechanical student and i am trying to generate a random rough surface (with specified ACF and Std Deviation) using 2D FIR filter in Matlab. I come across a paper that helps me doing that. For that, first i need to generate a input sequence composed of independent random numbers {?(I,J)}. The paper says its PSD must be a constant. I used matlab to generate independent r...

Hi experts I need to simulate wireless MIMO fading channel in both Gaussian and Rayleigh random variables. I have implemented the channel matrix H = h11 h12 h21 h22 where h11 h12 h21 h22 are independent Gaussian or Rayleigh random variables. Could somebody teach me how to introduce correlations among thoese random variables in terms of correlation coefficient? Thanks for any he...

Hi everybody; I want to learn about if it is possible rearrange a vector in MATLAB in a random manner. For example i have the vector=[1 3 5 8 7 0] and i want a new vector using the vector elements but different order i.e. new_vector=[0 7 3 1 8 5 ]; this order sould be random. Any idea? I think to use "randint" to regenerate indexes then create new vector using new index order. But problem is...

Dear all, I am working on trying to simulate a random signal of a given frequency range (say between 0 and 5000 Hz) in MATLAB. I have used signal generator apparatus in which I just select the kind of signal output (Sine or Random) and choose a frequency range. If I was to simulate the above in MATLAB, how could I do it? I would be really grateful for any help on this. Merry Christm...

Hi, I got a program as below which generates random binary codes (Phase 1.1). After that have to add parity bit to the codes(1.2). The next step is to generate error to the code, but it generates error ( Index exceeds matrix dimensions). Y is it so and some one got the right answer? %Phase 1.1 n=10;% # of bits b=round(rand(1,n));% creates random binary code disp('Random Da...

Hi, I am currently researching dithered quantization. Does anyone know of a commonly used pseudo-random number generator that is used to produce dither signals? The application is not spefic to audio or video or images, I am just trying to compare the statistical properties of random signals which are quantized using different PRNG's to generate the dither signal. thanks, Will

Dear Sir, I am working on Gaussian random Process, where I am stuck from few days because of the following two difficulties. 1. I have different segments of Gaussian distributed random sequences, of which two sequences among them are templates . I need to find the joint pdf and thereby marginal pdf between a segment and the templates. And thereby the probability of the segment bei...

Hi I am working on a simulink model of bluetooth DM1 packet transmission. I have used a random generator for the input and also have used binary symmetric channel with a certain error probability. The problem is that i dont know how to specify the initial seed values for both the random generator and the symmetric channel. What can be the appropriate seed values. I have tried the s...

Dear All, I would highly appreciate if you share your thoughts on the correctness of the method for calculating PAPR value of OFDM signal as described below. I am using NRZ random bits as the random input data where the n point IFFT outputs are x1,x2..xn(complex values) for one OFDM symbol. peakpower=max(abs(x1).^2,abs(x2).^2,..abs(xn).^2) avgpower=sum((abs(x1).^2,abs(x2).^2..abs(xn).^2)/n
