(due April 4, to be discussed on April 3)
Problem set for chapter 3: 3.2,3.5,3.15,3.22,3.26
(due April 11, to be discussed on April 10)
Problem set for chapter 4a: 4.2, 4.3, 4.6, 4.13, 4.18, 4.22,
(due April 25, to be discussed on April 24)
Problem set for chapter 4b: 4.23, 4.32, 4.39, 4.44 - 1, 4.53, 4.54
(due May 9, to be discussed on May 8)
Problem set for chapter 6: 6.5, 6.15, 6.22, 6.42, 6.62(1), 6.66,
Extension (1) of 6.66: Redo 6.66 without the optimal bit-by-bit detector. That is, just assume the continuous output channel y=x+n, where x is binary antipodal and n is white Gaussian noise.
Extension (2) of 6.66: Redo Extension (1) for 4PAM modulation. NOTE: Do not redo 6.66 itself for 4PAM as this is much more difficult than redoing extension (1) for 4PAM.
Use Matlab to visualize the results.

Problem for chapter 8: Description, encoder, decoder
Note: This problem is asusmed to be done entirely in the discrete domain. Thus, no continuous time signals need to be created.

Problems for chapter 9: 9.12 (a)-(c), 9.14, 9.15, 9.23, 9.36, 9.41, 9.46
(to be discussed on May 22)
Problems for chapter 10: No problems
Problems for chapter 11: 11.2, 11.3, 11.5 (note typo in book: 11.2-11 and 11.2-12 should be 11.2-20 and 11.2-21).
Extra problem 1: Redo Section 11.1-1 for unequal channel gains (the alpha values) and unequal input powers at the different channels. Find the optimal power allocation as a function of the alpha values.
Extra problem 2: For the same setting as in extra problem 1, assume that the "signal combiner and detector" in figure 11.1-1 simply adds all signals up with uniform weighting. Find the optimal power allocation as a function of the alpha values. Assume that all phases ("phi") in (Eq 11.1-2) are zero, or equivalenty, that they are compensated at the transmitter.

Problems for chapter 13: 13.1 (a)-(b), 13.4 (a)-(d), 13.6, Prove eq. 13.5-36.
Hint 1: In 13.4 (d), the data rate is not given. Assume a data rate of 1 bit/sec. Use a multicarrier system with frequency spacing 1/T.
Hint 2: The text between eq 13.5-35 and 13.5-36 is sufficient for proving eq 13.5-36.
Hint 3: To learn the most of "prove eq. 13.5-36", try to do this via "first whiten the noise, then apply the matched filter".

Problems for chapter 14: 14.5, 14.11 (Hint: Use eq. (13.4-13))
Problems for chapter 15: 15.4, 15.10, 15.18
Problems for chapter 16: 16.2, 16.3, 16.22 (Hint: start by sketching a figure similar to to the one in Figure 16.2-4)
