What are some of the advantages and disadvantages of TDD vs FDD? Here is what I can think of:
TDD advantages:
utilizes same channel when channel is not varying quickly (CSI can be estimated and is known for TDD on both ends)
in-band filter is simpler (does not change in varying datarate scenarios between the uplink and downlink)
TDD disadvantages:
requires precise time sync
FDD advantages:
time sync does not have to be that precise
FDD disadvantages:
CSI needs to be estimated at receiver, meaning transmitter requires CSI feedback for optimal communication/operates without CSI
Please add to/correct the above =)
