1. A receiver to be used in a broadcast network, the receiver comprising:
a memory storing program instructions; and
a processor, upon executing the program instructions, configured to:
receive a data frame including a non-payload region and a payload region, the payload region comprising a first set of orthogonal frequency domain multiplexing (OFDM) symbols and a second set of OFDM symbols,
wherein the first set of OFDM symbols is for a first set of user devices having a first set of delay spreads and the first set of OFDM symbols has a first transform size and a first cyclic prefix size, and
wherein the second set of OFDM symbols is for a second set of user devices having a second set of delay spreads different from the first set of delay spreads and the second set of OFDM symbols has a second transform size and a second cyclic prefix size, the second cyclic prefix size being different than the first cyclic prefix size; and
decode the first set of OFDM symbols.
