Abstract

The mobile communication systems services are shifting from voice conversation to data transmission through the internet. The information transferred over the Internet is becoming increasingly rich, there will be a demand of peak data transmission rates of around 100Mbps ˜1Gbps even in mobile communications systems. However, as the data transmission rate becomes higher, the peak transmit power becomes larger. To decrease the peak transmit power, a multi-hop virtual cellular network (VCN) that can significantly reduce the transmit power was proposed. This paper introduces the multi-hop maximal ratio combining (MHMRC), to the VCN in order to decrease the route total transmit power, improve the transmit power efficiency degradation caused by the carrier frequency difference between the control and the data communication channels for VCN. It was shown that the MHMRC diversity gain decreases. MHMRC diversity can reduce the number of hops in the rout.
