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.
