Advantages of OFDM:-
Convert selective fading channels into flat fading channels
Disadvantages of OFDM:-
Simplicity in H.W implementation
ISI free Communication
LTE Physical Channels
LTE Transport Channels
LTE Logical Channels
The LTE physical channels vary between the uplink and the downlink as each has different requirements and operates in a different manner.
The LTE transport channels offer information transfer to medium access control (MAC) and higher layers.
Control,Paging,Common Control,Multicast Control
