Description
  • Determine the causes of impairment, such as attenuation, distortion, and noise, for guided and unguided communication channels.
  • Describe the operation of different analog modulation techniques and determine the resources for each technique, such as bandwidth and power, and compute the corresponding performance and efficiency.
  • Describe the operation of different digital modulation techniques, including the major modules such as ADC, I-Q modulators, bit-rate versus symbol rate, and constellation diagrams both for baseband and bandpass systems. Determine the required bandwidth and overall performance of bit error rate as a function of bit-energy/noise power density.
  • Explain different types of physical transmission channels used for wireless and wireline communication systems. Justify the reason for multiplexing in both wireless and wireline systems, and describe briefly the multiplexing techniques in time-division, frequency-division, space-division, etc.
