Part A

Advanced 3G systems like LTE and 802.16e (WiMax) use OFDM. So do all potential 4G systems like LTE-Advanced and 802.16m. Even digital video broadcasts are now OFDM. Prior 3G standards, like UMTS and EVDO, predominantly used CDMA.( 3-4 paragraphs)

  • Why has this shift occurred?
    • Do you feel it is for the better?
  • What specific cross-layer optimizations are unique to OFDMA? 
    • How have these affected this migration?
  • Why did standards such as GSM and TDMA flourish before?
    • Would a different solution have made better sense?
  • ◦What trends do you see?APA format


Part B


Different access methods, such as OFDMA, SDMA, TDMA, CDMA, and FDMA, rely on cross-layer optimization to different degrees. The most common cross-layer issues are scheduling modulation type and setting power control. Complete the following for your assignment:

  • Describe the advantages of each access method in doing cross-layer optimization correctly.
    • What are the costs of doing it poorly? (2-3 pages) APA Format
