Project 2: Error Rate and Phase Jitter in 16-QAM Modulation (a) For a 16-QAM modem, use MATLAB to plot the probability of symbol error, Ps , versus Es /N0 , where N0 is the variance of the noise and Es is the average energy per transmitted symbol. (b) Repeat part (a) for a 10 phase error at the receiver, and compare the results with those of part (a). What are the SNRs (in dB) for the probabilities of symbol error of 10 2 and 10 3 (c) Repeat parts (a) and (b) for 64-QAM. Project 3: Design of Raised Cosine Matched Filters The impulse response of a pair of matched lters that results in a raised cosine spectrum is given in Eq. (7.5.2). A simple way to design these lters is to window the sampled version of the lter impulse response and design an FIR lter with the windowed sampled impulse response. In this project we examine the time and frequency response of this approach for a particular design speci cation. Assume that the rolloff factor of the raised cosine pulse is 0.1, the length of each FIR lter is 23 taps, and the sampling rate is T /4, with 1/T the transmission rate of the pulses. (a) If the design uses a rectangular window, sketch the overall back-to-back impulse response of the transmitter and receiver lters. What is the variance of the ISI caused by the lter if the center tap is normalized to 1

Turbo codes are among the most important developments of coding theory since the eld was founded. As we have already mentioned in Section 14.1, very long codes can approach the Shannon limit (channel capacity). However, the brute force decoding of such long codes is prohibitively complex. Turbo codes were the rst practically used codes that came close to the Shannon limit using reasonable effort. Berrou et al. [1993] created very long codes by a combination of several parallel, simple codes. The codes are interleaved by a pseudorandom interleaver. The vital trick now lies in the decoder: because the code is a combination of several short codes, the decoder can also be broken up into several simple decoders that exchange soft information about the decoded bits and thus iteratively arrive at a solution. The random interleaver in the code approximately realizes the idea of a random code, so that the total codeword has very little structure. This has the following advantages: Interleaving increases the effective codelength of the combined code. In other words, it is the interleaver (whose operation can easily be reversed), and not the constituent codes, that determines the length of the codes. This allows the construction of very long codes with simple encoder structures. The special structure of the total code i.e., the composition of separate constituent codes makes decoding possible with an effort that is essentially determined by the length of the constituent codes.

If you purchased a copy of Windows 7 on DVD at a retailer or online store (or e-tailer, as we like to call them), you can install Windows 7 using Microsoft s simpler new Interactive Setup Wizard, which guides you through a series of steps required to get Windows 7 up and running. There are three primary ways to install Windows 7 using Interactive Setup: a clean install, where Windows 7 will be the only operating system on the PC; an upgrade, where you upgrade an existing operating system to Windows 7, replacing the old with the new; and a dual-boot, where you install Windows 7 alongside your old operating system and use a boot menu to choose between them each time you reboot. You ll look at all three methods in this chapter, in addition to a fourth and related (but secret) installation method: a clean install using Upgrade media.
