| Abstract(in English) | Multi-hop relaying can extend communication range using limited transmit power, and improve the area spectral efficiency. However, it brings considerable degradation of end-to-end error rate performance due to error propagation along the hops. Cooperative relaying, in which multiple stations relay the received signal using transmit diversity techniques, can recover the errors unless all the relay stations do not receive the signal correctly, and improve the end-to-end transmission performance. In this paper, the FER performance of multi-hop cooperative networks is analyzed by using state transition. Theoretical analysis reveals that the FER performance can be kept almost constant, or even improved with increasing the number of the hops. The computer simulation results closely agree with the analysis. And also, it is revealed that this multi-hop cooperative networks is suitable for spectrum sharing because of its good transmission performance and low transmission power. |
