| Summary: | 碩士 === 龍華科技大學 === 電子工程研究所 === 96 === IEEE 802.16j is the standard that enjoys the most attention at present. By deploying Relay Stations (RS) in appropriate locations to enhance the throughput of the IEEE 802.16 users, and by expanding the coverage range of the wireless communications, it utilizes Relaying technology to reach an uniform transfer data rate. When we use the Multi-Hop to transmit data on Relay Path, as the number of HOP increases, any data transmission error will cause longer delay times as well as congestions. IEEE 802.16j proposed three Relay Network transmission technologies to resolve the data transmission problems. However, these three methods have their drawbacks such as longer transmission delay times and waste of transmission bandwidths. Therefore this paper proposes a Pipelined system to improve the performances of the three original transmission technologies. We will use simulation to verify that the proposed method can indeed improve the shortcomings of the original methods.
