Matlab Hmwk #3: P&M Prob. 7.29, 7.30. DUE
DATE: Friday, Dec. 7 (last day of classes) Matlab 3: Two text
Problems from Chap. 7. .
NOTE: Prob. 7.30. f_1 = 1/128 NOT 1/18  typo!
Also, plot magnitude of DFT in each case.
Note: Prob. 7.29, for parts (b) and (c), use
reconstruction formula (7.1.13) on pg. 453.
Prescription for what
to plot ; VIP: use Matlab code below
SpectrumReconstruction.m Key Matlab code for Prob.

My notes on
Frequency Domain Sampling Notes (Chap 7) ;
(b) Use N=21 rather than N=20, and use the sequence
x[n]=a^nD, n=0,1,...21, where D=(N1)/2=10. Multiply
X(w) in problem statement by linear phase term exp(jDw)
with D10.
(c) Use N=101 rather than N=100, and use the sequence
x[n]=a^nD, n=0,1,...100, where D=(N1)/2=50. Multiply
X(w) in problem statement by linear phase term exp(jDw)
with D=50.
(e) Use the timedomain aliasing formula in (7.1.4) on
page 450. Use three terms: x[nN] + x[n] + x[n+N], for
n=0,1,...N1. Plot what this formula yields on the same
graph as a plot of the IFFT of N samples of the original
spectrum in the interval from 0 to 2pi.

Statement, Modifications
; M15.m . Recommend against using the
matlab command "xcorr" to do the crosscorrelation  just
use convolution to do correlation as in the CDMA examples
posted at the course web site: ryx = conv(y,x(end:1:1))
and throw away the first first M1 values of ryx (where M
is the code length) since those correspond to negative
timeshifts and the problem only asks you to plot for
positive timeshifts.

It may be helpful to review material from the
undergraduate junior level course on signals and systems:
ECE
301 Signals and Systems We may occasionally look at
notes posted there, especially towards the beginning of
the course.
Your primary homework assignment is to solve my old
exams (posted below) without looking at the solutions in a
timed setting. You can look at the solutions before and
after attempting the exam, but it is important to work
through them without looking at the solution. A few
students have asked for homework problems out of the
textbook, but I think the best homework, in terms of
preparing for the exam, is to work through my old exams.
Some history and miscellaneous course information:
This course emphasizes applications of Digital Signal
Processing (DSP) in compact disc (CD) players, wireless
communictions including OFDM and CDMA, radar, and speech
processing. Professor Zoltowski has taught this course the
Fall of every year since 1990.
