What are the differences in channel allocation problem in FDMA/TDMA-based system versus CDMA-based system? Explain clearly.
What will be an ideal response?
In FDMA/TDMA system, the number of frequencies and time slot is limited.
Channel allocation problem in FDMA/TDMA is how to efficiently allocate the
frequency or time slot to support more users. While in CDMA system, the number
of possible codes indicates the number of users that can be supported. Hence, the
allocation problem in CDMA is converted to how to control the transmission
power so as to minimize the interference.
