| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Cooperative relaying is a promising technique that exploits neighboring stations to accommodatingly relay the data toward the destination in order to achieve spatial diversity gain. It has been reported that by introducing cooperative relaying into communication between an isolated source-destination pair, the error rate or spectral efficiency is generally improved. However, it is not intuitively clear whether cooperative relaying can improve the performance in interference-limited environments because simultaneous transmissions of multiple stations increase the number of interference signals. Assuming the most fundamental cooperative relaying consisting of only one relay station, spectral efficiency of cooperative relaying interference-limited environments where a given channel is spatially reused is investigated. Numerical results reveal that cooperative relaying does not always have the superiority over non-cooperative single-hop and 2-hop transmissions in terms of spectral efficiency. |
