Consider a point-to-point radio link between two highly directional antennas in a stationary environment. The antennas have antenna gains of 30 dB, distance attenuation is 150 dB, and the receiver has a noise figure of 7 dB. The symbol rate is 20 Msymb/s and Nyquist signaling is used. It can be assume that the radio link can be treated as an AWGN channel without fading. How much transmit power is required (disregarding power losses at transmitter and receiver ends) for a maximum BER of 10-5, when using:a. Coherently detected BPSKb. By how much must transmit power be increased to maintain the maximum BER of 10-5 if the channel is flat Rayleigh fading
Define a function that takes as input parameters a function handle f, start and end values a and b, and a number of steps n. The function should compute and return the x and y values of the maximum of the function over the range a to b.
MATLAB has a built-in ability to perform mathematical operations on complex numbers. However, there are times when it is useful to treat complex numbers as a structure. Write a set of functions with the following capability and a script to verify ..
The value of acceleration due to gravity (g) on a point 10,000 kilometers above sea level is about 1.49 meters/second2. How much will an object, which weighs 98 newtons on the surface of Earth, weigh on this point
What could the contaminant/toxicant/pollutant be and where could the contaminant have likely come from - explain how all the information provided in the case study backs up your Diagnosis.
Create a MATLAB function named "problem1", which accepts a number, a vector OR a matrix input and returns 4 outputs in this order related to the input: arithmetic average mean, standard deviation, median, max. The numbers you return for each outpu..
Compute the power spectral density vector. Plot the spectrogram using the same parameters as in lecture.
Write a script to solve the following systems of equations using both matrix left division (\) and the inverse matrix method and Show that you have tested your MATLAB code appropriately
In this MATLAB exercise, we will explore downsampling and upsampling a discrete-time signal corresponding to a piece of music. To start, type load handel. In your workspace, you should now have a vector y of length 73113. Play this piece of music ..
A computer cannot store an entire function in its memory. Typically it stores the values of the function at a finite number of points. Pick values of a, b, v, N, and Δt, and write a program to implement this process. Be sure to leave a, b, v, N, an..
Write a user-defined MATLAB function that calculate the condition number of an (nxn) matrix by using the 1-norm. for the function name and arguments use c = condNum_one(A).
Write the numerical values of temperature and the corresponding value of the analytical solution to this problem, T=xy, at each of your grid points, to a text file.
