==MCPC== SCPC was the successor '''multiple channels per carrier''' ('''MCPC'''). With MCPC, several subcarriers are combined or multiplexed into a single bitstream before being modulated onto a carrier transmitted from a single location to one or more remote sites. This uses [[time-division multiplexing]] (TDM) as well as [[frequency-division multiplexing]]. It is a [[retronym]] of sorts, as it was the only way [[radio network]]s were transmitted ("[[Piggybacking (data transmission)|piggyback]]ed" on [[television network]]s) until SCPC. In [[digital radio]] and [[digital television]], an [[DAB ensemble|ensemble]] or other multiplex or multichannel stations can be considered MCPC, though the term is generally only applied to satellites. The major disadvantage of MCPC is that all of the signals must be sent to a single place first, then combined for retransmission — a major reason for using SCPC instead.
