when i generate a random data in matlab and i want to apply a lowpass filter to these data , how can i identify it's maximum frequency in order to determine the sampling frequency that i will use as an input to my filter
for example :
x=randint(1,10); %%% random bits
a=modem.pskmod(4); %%%% (...)

Hi there, I have been simulating a system in matlab.
So Im not good with communication basics and im very new to it.
Here is the problem.
Im using rectpulse function from matlab, the it needs a sampling rate to generate rectpulse from random bits.
So the sampling rate is calculated using, (...)

generate a random bit stream. Group 6 bits into one complex symbol. The complex symbol should be one of the points in the constellation. You need to first define the constellation points and just map 6 bits into one of the constellation point. Does this answer your question? or you want to do more?

Please help guys.. i need to perform the run and correlation property on a stream of bits that has been pseudorandomly generated.
I have used the following piece of code: e.g x= randn(10,1)>0.5 to generate random bits of 0's and 1's. Is this the correct way of doing it or do i need to (...)

Being new to matlab I 've been struggling to simulate QPSK modulation for the IEEE 802.15.4 in Simulink. So, I generate a random integer number from 0-15 which in order to convert to binary i pass through a integer to bit converter block with an output of 4 bits. Then I want to map the output to 32 bit (...)

A direct way to check if the sequency is truly random is to use auto-correlation function in matlab. A true random sequence should generate a Dirac type auto-correlation output, whose Fourier Transform should give you 'white' spectrum density function.
In matlab, you can use xcorr(A), where A is your (...)
