It is widely known and accepted that multicarrier communication is effective in frequency selective channels if resource allocation strategies are used, namely per-subcarrier adaptive modulation and coding. We discuss its efficiency for uniform resource allocation in terms of fundamental information-theoretic measures. These results are relevant to broadcast systems and, more generally, systems which cannot rely on a feedback channel.

Abstract
It is widely known and accepted that multicarrier communication is effective in frequency selective channels if resource allocation strategies are used, namely per-subcarrier adaptive modulation and coding. We discuss its efficiency for uniform resource allocation in terms of fundamental information-theoretic measures. These results are relevant to broadcast systems and, more generally, systems which cannot rely on a feedback channel.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
