Improved transmission scheme for reliable communication in cell boundary
In a wireless communication system, the performance of the system is degraded due to the attenuation of the signal by path loss when a user is distant from the base station. For improvement of the system in this case, a new scheme is proposed. In conventional schemes, the source can transmit to the destination belonging to own cell coverage. In the proposed scheme, the destination can receive the additional signal from another base station through multiple relays. Therefore, the proposed scheme provides higher diversity gain and better performance than the conventional scheme.
