For Eb/No values of [-3,35], generate data bits that would be transmitted via a BPSK communication system with Rayleigh fading channel and AWGN noise. At the receiver side: a. Equalize the received signal (simply by dividing the received signal by the channel coefficients).
b. Design the BPSK demodulator (if received signal is +ve then the data bit=1 otherwise the data bit =0)
c. Count the number of bits in error and the BER.
d. Compare with the theoretical BER in AWGN channel.

answer: a

a is the answer

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
