EXAMPLE 6.7
Consider an M-ary system with the number of symbols M=16, and the roll-off factor a=
Discuss this M-ary system, vis-à-vis the corresponding binary system, for various scenarios.
Solution
1
Design an oscillator circuit using the arrangement in Fig. 4 (namely, find C+1=C+2).
Fig. 4 shows that we are using a pair of 2N5485 JFET. However, you are supplied
with two J112 (or J113) to be used here. Use datasheet for J112 (or J113) to
determine the needed capacitances. The oscillation frequency is considered to be
1 MHz. Use L₁ = L₂ = 112 μH. Furthermore, assume Cr=200 pF and Re = 300 .
Is the assumption Cf >> CGS&CGD valid?
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.
