Abstract

This paper introduces a new approach for enhancing relay link quality. Two types of antennas were proposed at the relay node (RN). The first type is the directional antenna, which is directed toward the base station to achieve the maximum relay location range and improve the relay link quality, thereby reducing outage probability by increasing relay link capacity. The second type is the omni-directional antenna, which is used for the exchange of information between the RN and attached users. The optimum relay location was derived, thus ensuring the maximum spectral efficiency and best received signal strength over the relay link and cell edge. An improvement of 32% in spectral efficiency and a difference of-62 dBm to -50dBm in received signal strength at the relay link has been observed while considering Interference from neighboring cells. An ATDI simulator, which manages the digital cartography for the first tier of interference in urban areas, verified the numerical results.
