DS-CDMA fornece suporte flexível para taxas de bits baixas a altas de serviços multimídia mediante solicitação de um usuário específico. Uma expressão de capacidade simples é derivada para um link reverso controlado por energia de DS-CDMA multicódigo ortogonal com múltiplas conexões. Verifica-se que um usuário multicódigo ortogonal com múltiplas conexões é equivalente a um usuário de conexão única, mas com um fator de espalhamento reduzido por um fator do número total de códigos paralelos e uma energia de sinal necessária por símbolo para interferência mais ruído taxa de densidade do espectro de potência, que é a média obtida em múltiplas conexões. Além disso, o uso da diversidade de antenas é equivalente ao uso de um fator de espalhamento mais alto aumentado por um fator do número de antenas.

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.
