DS-CDMA fournit une prise en charge flexible du débit binaire faible à élevé des services multimédia à la demande d'un utilisateur spécifique. Une expression de capacité simple est dérivée pour une liaison inverse à puissance contrôlée de DS-CDMA multicode orthogonal avec plusieurs connexions. Il s'avère qu'un utilisateur multicode orthogonal ayant plusieurs connexions est équivalent à un utilisateur de connexion unique, mais avec un facteur d'étalement réduit d'un facteur du nombre total de codes parallèles et une énergie de signal requise par symbole vers interférence plus bruit. rapport de densité spectrale de puissance qui est la moyenne prise sur plusieurs connexions. De plus, l'utilisation de la diversité d'antennes s'avère équivalente à l'utilisation d'un facteur d'étalement plus élevé augmenté d'un facteur du nombre d'antennes.

Abstract: DS-CDMA provides a flexible support for the low-to-high bit rate of multimedia services upon a specific user's request. A simple capacity expression is derived for a power-controlled reverse link of orthogonal multi-code DS-CDMA with multiple connections. It is found that an orthogonal multi-code user having multiple connections is equivalent to a single connection user, but with a spreading factor reduced by a factor of the total number of parallel codes and a required signal energy per symbol-to-interference plus noise power spectrum density ratio which is the average taken over multiple connections. Furthermore, the use of antenna diversity is found equivalent to the use of higher spreading factor increased by a factor of the number of antennas.
