10pts: Matlab:
From Problem 1 of homework 6, repeated below:
Generate a random binary PAM transmit signal of -1 and + 1 volts of length 100.
Simulate the transmit signal being sent over a channel with AWGN with an Eb/No of 3 dB.
Plot the received signal constellation using a red o to represent when a logical 0 was sent and a
blue * to represent a logical 1 was sent
Question (1) Increase the Eb/No to 7 dB. Approximately what length of the signal do you need to get
consistently within ~5% of the theoretical value for the bit error rate?
a) Guess without doing any simulations
b) Estimate by trial and observing the results.
(1) A baseband PAM communication channel bandwidth is 100 KHz and has a noise power spectral density
of 10^-9 W/Hz. The channel loss between the transmitter and receiver is 25dB. The application requires a
bit rate of 500 Kbps and BER of less than 10^-5. The system uses raised cosine pulses with a roll-off factor
of 0.25. Determine the minimum transmit power required.
(2) Continuing problem 1. Everything for the previous problem stays the same BUT the best Power
Amplifier you can afford has a maximum output power of 10 Watts. What will be estimated BER for the
system?
