  ECET 380 Week 1 iLab Simulation of a Fundamental Communication System  For more course tutorials visit   www.newtonhelp.com   Key Results:   Key Conclusions (technical):   Key Conclusions (critical thinking):   I.OBJECTIVES 1.   Introduction to the MATLAB Communications Toolbox. 2.   Use various functions of the Communications Toolbox to simulate a fundamental communication system. 3.   Using stem plots, scatterplots, and BER plots, observe various characteristics of the transmitter, channel, and receiver in both ideal and noisy conditions. II.PARTS LIST  Equipment: IBM PC or Compatible with Windows 2000 or Higher Software: MATLAB Version 7.1 or Higher III. INTRODUCTION The MATLAB software is a popular and powerful tool frequently used across varied industries in the simulation and modeling of systems, wireless and otherwise. Through the use of MATLAB, systems behavior can be predicted and analyzed in conditions as close to practical as possible. Of special interest to the study of wireless systems is MATLAB’s Communications Toolbox. This Toolbox can be used to simulate, evaluate and analyze an entire wireless system from end to end. Models are developed to include the entire system, from the baseband signal conditioning, to modulation schemes, through the effects of stochastic radio channels, and finally to demodulation and error calculations. Having the ability to use MATLAB’s Communications Toolbox gives the aspiring wireless communications engineer a solid background for future investigation in this fast- expanding field. IV. A. Overview of the Communications Toolbox    1.   Open MATLAB and familiarize yourself with the Default Layout, which includes the Current Directory, Command History and Command Window. You will be working primarily in the Command Window, but the other windows may provide useful information in the future. 2.   The Command Window is a command line environment, much like DOS or UNIX. You will type all commands in this lab at the >>  prompt. Following each command, you will need to hit the Enter  key. Also, if you are working in the Citrix environment, t here may be a lag in MATLAB’s response.  Some operations are VERY processor intensive  –   just be patient. 3.   ------------------------------- ECET 380 Week 2 iLab Simulation of a Rayleigh Channel For more course tutorials visit   www.newtonhelp.com   Simulation of a Rayleigh Channel Summary (two sentences): Simulated and analyzed the effects of flat fading Rayleigh channels on transmitted signals. Simulated and analyzed the effects of frequency selective Rayleigh channels on transmitted signals.   The radio channel that links the transmitter and receiver in wireless communications applications can be a hostile and complicated medium. Characteristics of the channel may lead to security  breaches, limit the application’s throughput, or severely degrade signal quality if the system is not properly designed. The causes of these deficiencies are primarily due to two factors: Doppler Shift, which is caused by motions of the mobile device or objects in the radio channel, and Multipath Fading, which results from scattering of the transmitted electromagnetic waves. The radio channel is usually characterized as one in which its statistics are modeled as Rayleigh or Rician distributions. Open MATLAB and familiarize yourself with the Default Layout, which includes the Current Directory, Command History, and Command Window. You will be working The Command Window is a command line environment, much like DOS or UNIX. You will type all commands in this lab at the >> prompt. Following each command, you will need to hit the Enter key. Also, if you are working in the Citrix To get started, type in: >> 1.   Scroll UP until the comm\comm. Select this entry. 2.   Scroll UP again, and select rayleighchanunder the Channels main topic. Explore this section, along with doc rayleighchanto familiarize yourself with the function.  3.   What information is available? Summarize each property & parameter. Identify Read-Only (R) and Writable (W) properties. 4.   At the prompts, type in the following (press Enter after each line): 5.   What non-zero parameters of the channel are displayed? Record their values. 6.   Why is PathDelays = 0? Only one Path B. Generate and Plot Rayleigh Channel Power 1.   Take a screen shot that shows your plot to include with your lab report submission. 2.   ------------------------------- ECET 380 Week 3 iLab Antenna Design For more course tutorials visit   www.newtonhelp.com   Antenna Design   Key Conclusions (technical):   Key Conclusions (critical thinking):   I.OBJECTIVES
