| Zusammenfassung: | The present invention proposes signal processors, communication units, wireless systems and methods related to the transmission and reception of data streams in DVBs with consideration of limited capacity and the limitation of statistical multiplexing gain. A method for mapping one or more logical channels to a radio frequency channel in a communication system is described. The method includes the following processes: determining a logical channel type from a plurality of logical channel types; and mapping at least one logical frame of the determined logical channel type based on the determined logical channel type, to at least one physical frame in at least one radio frequency (RF) channel.
통신 시스템에서 하나 혹은 그 이상의 논리 채널들을 무선 주파수 채널에 매핑하는 방법이 설명된다. 상기 방법은 다수의 논리 채널 타입(logical channel type)들로부터 논리 채널 타입을 결정하는 과정과, 결정된 논리 채널 타입을 기반으로 상기 결정된 논리 채널 타입의 적어도 하나의 논리 프레임(logical frame)을 적어도 하나의 무선 주파수(radio frequency: RF) 채널에서 적어도 하나의 물리 프레임(physical frame)에 매핑하는 과정을 포함함을 특징으로 한다. |
