Abstract

In a multi-hop virtual cellular network (VCN) proposed for high data rate mobile communications, the signal transmitted from a mobile terminal is received by the multiple wireless ports distributed in a virtual cell and relayed to the central port that acts as a gateway to the core network. Multi-hop maximal ratio combining (MHMRC) can be used to reduce the total transmit power of the wireless ports along a route by combining the signals received from all the previous ports. However, the received signals from far previous ports may be very weak and not effective in diversity combining. In order to reduce the number of signals to be combined, we apply the hybrid selection/MRC (H-S/MRC) diversity technique. We evaluate by computer simulation the power efficiency of the multi-hop H-S/MRC and compare it with that of MHMRC.
