I want matlab code to plot 8-bit FSK ( frequency shift modulation ) for bit error rate
Design a matlab code that: 1-play sound 2- add noise to the sound 3- filter the noised signal using fir or iir filter Note: FIR: Finite impulse response filter IIR: Infinite impulse response filter Please make code simple. don't copy other from other codes.
write a MATLAB program to demonstrate the operation of the quadrature amplitude modulation and demodulation schemes.
Use MATLAB to plot the AM DSBSC modulated signals with modulation index m=0.25,0.5,0.8,1.0,1.2,1.5,2.0 with carrier signal c(t)=20cos(2pi20000t) and massage signal m(t)=Vm cos(2pi3000t) along with the envelope.
1 Question 5 pts What is the coherent demodulation? Question 1 pts What kind AM modulation can transmit the information signal in maximum power if the carrier signal power is fixed? Question 1 pts What kind AM modulation has the narrowest signal band to transmit the same information signal? Question 10 pts Search om Internet. What is the VSB, which is a kind of AM modulation used in TV means? at are the advantages and disadvantages according to the information...
I am stuck with the problem of finding the average input
power(dun know how to find bar x(t)^2), with the formula below.
Please help me and finish the question, and also in part b, the FM
problem(how to find Pr). Thx.
We were unable to transcribe this imageSNR3p SNR,-β2 for FM for FM Question 2 A communication channel has 20-dB attenuation and additive white Gaussian noise with power spectral density of 3x103 WHz. The bandwidth of the message signal is...
This question should be solved by MATLAB. - Generate an analog signal. (This should be an audio, any audio can be used.) - Analyze frequency spectrum of this analog signal. - Modulate it. (AM Modulation can be used) - Send the modulated signal over a wireless channel. (Before sending the signal, a noise should be added.) Thank you already for your help!
Consider the message signal m(t):a. Sketch the AM signal u(t)=[ A + m(t) ] Cos(wct) for modulation indexes μ = 0.5 and μ = 2.0 by assuming the carrier frequency to be much higher than the bandwidth of m(t) b. Determine the efficiency percentage (η = ps/pt) for μ = 0.5. Herein, Ps and Pt are sideband and total powers respectively, and Pt= Ps + Pc , in which Pc is the carrier power. Hint : Take into account the Parseval's property. c. If the AM waveforms corresponding...
