| Abstract(in English) | There have been strong demands for higher speed data transmissions in mobile communications. To reduce the peak transmit power while increasing the data transmission rates, authors proposed a wireless multi-hop virtual cellular system. In the multi-hop virtual cellular system, the transmitted signal from a mobile terminal is received by wireless ports distributed in a virtual cell and relayed via wireless ports using a wireless multi-hop communication technique to a central port connected to the network. We proposed a channel allocation algorithm based on the dynamic channel allocation (DCA) using the channel segregation algorithm. In DS-CDMA, Rake receiver can combine the delayed versions of a signal. As the number of propagation paths increases, the Rake combining effect also increases, but, the inter-path-interference increases, thereby degrading the transmission performance. In this paper, we evaluate the DCA failure rate in a frequency selective fading channel for DS-CDMA multihop virtual cellular system. |
