Neste artigo, é discutida a coexistência do sistema de compartilhamento de espectro TDMA e W-CDMA (sistema sobreposto TDMA/W-CDMA) com a arquitetura celular. Neste sistema, ambos os sistemas partilham a mesma banda de frequência para melhorar a eficiência do espectro. A taxa geral, a taxa de erro de bit (BER) e a eficiência do espectro do sistema são calculadas para o link direto (link descendente) na presença do canal AWGN. Levando em consideração a perda de caminho e a perda de desvanecimento de sombra neste sistema com arquitetura celular, o W-CDMA aplicando cancelamento de interferência (IC) mostra uma diferença substancial na eficiência do espectro, o sistema sobreposto pode fornecer uma taxa geral maior e maior eficiência do espectro do que um único sistema baseado em acesso múltiplo, como sistema TDMA ou sistema W-CDMA. O cancelamento de interferência pode melhorar significativamente o BER do sistema sobreposto de espectro.

Abstract: In this paper, the co-existence of TDMA and W-CDMA spectrum sharing system (TDMA/W-CDMA overlaid system) with cellular architecture is discussed. In this system, both systems share the same frequency band to improve the spectrum efficiency. Overall rate, bit error ratio (BER) and spectrum efficiency of the system are calculated for the forward link (down-link) in the presence of AWGN channel. Taking into account the path loss and shadow fading loss in this system with cellular architecture, W-CDMA applying interference cancellation (IC) shows a substantial difference in spectrum efficiency, the overlaid system can provide a greater overall rate and higher spectrum efficiency than a single multiple access-based system such as TDMA system or W-CDMA system. The interference cancellation can significantly improve BER of the spectrum overlaid system.
