NWIT 229 - Wireless Communications

(G only)

An introduction to modulation and demodulation theory and circuits used in amplitude, phase and pulse code modulation. Analysis of receiver and transmitter characteristics including sensitivity, noise, tuning and alignment techniques, properties of transmission lines, and impedance matching will be incorporated. This course also covers the fundamentals of Base Stations, Mobile Switching Centers, and how the system functions as a whole (ASK, FSK, PSK, QAM, CDMA, W-CDMA, TDMA, GSM, PCS, CDPD, and the third-generation [3G] digital technologies). PREREQUISITE(S): NWIT 150  and NWIT 151 . Three hours lecture, three hours laboratory each week. Formerly NW 229.

4 semester hours

Course Outcomes:
Upon course completion, a student will be able to:

  • Describe, discuss, and explain the characteristics, advantages, and disadvantages of amplitude, frequency, and pulse modulation.
  • Analyze the composition of complex waveforms and describe the operation of AM and FM transmitters and receivers.
  • Describe construct basic communication circuits.
  • Describe amplitude modulation, AM waveform, percent of modulation, sidebands, and bandwidth.
  • Describe angle modulation, frequency modulation, modulation index, sidebands, and bandwidth.
  • Describe the communication system, input/output devices, transmitter, channel, noise, receiver, and tuning radio transmitter and receiver.
  • Explain the advantages of the use of repeaters and cellular systems for mobile communications and perform typical calculation with these systems.
  • Describe digital modulation and modems, multiplexing and multiple access, frequency-division multiplexing and multiple access (FDM/FDMA), time-division multiplexing and multiple access (TDM/TDMA), spread-spectrum systems, and code-division multiple access (CDMA).
