OFDM (Orthogonal Frequency Division Multiplexing) e CDMA (Code Division Multiple Access) estão sendo usados para permitir acesso móvel de banda larga sem fio sob severo desvanecimento de múltiplos caminhos em IMT-2000 e WLAN (Wireless Local Area Networks) de banda de 5 GHz, respectivamente. Espera-se que ambos desempenhem papéis importantes nos futuros sistemas de comunicação móvel de banda larga, como o celular de quarta geração e a WLAN de banda larga de próxima geração. Este artigo apresenta uma visão geral dos recursos das tecnologias OFDM e CDMA e discute suas funções nos futuros sistemas de comunicação móvel de banda larga. Ele sugere uma abordagem OFDM/CDMA combinada com adaptação de link e SDM (Space Division Multiplexing) sobre canal MIMO (Multiple Input Multiple Output) para alcançar alta taxa de transmissão e melhorar a eficiência de utilização de frequência para alta capacidade do sistema.

Abstract: OFDM (Orthogonal Frequency Division Multiplexing) and CDMA (Code Division Multiple Access) are being used to enable broadband mobile wireless access under severe multipath fading in IMT-2000 and 5 GHz band WLAN (Wireless Local Area Networks), respectively. Both of them are expected to play important roles in future broadband mobile communication systems such as fourth generation cellular and next generation broadband WLAN. This paper overviews the features of OFDM and CDMA technologies and discusses their roles in future broadband mobile communication systems. It suggests an OFDM/CDMA approach combined with link adaptation and SDM (Space Division Multiplexing) over MIMO (Multiple Input Multiple Output) channel to achieve high transmission rate and to improve frequency utilization efficiency for high system capacity.
