摘要

本文研究了上行同步多载波码分多址的性能。通过信令控制可以保持上行链路传输中的同步。并与异步系统进行了性能比较。数值计算结果表明,同步传输技术可以提供比传统异步传输更好的性能,特别是对于指数衰减的多径强度分布。

Performance of uplink synchronous multi-carrier CDMA in wireless communications
This paper studies the performance of the uplink synchronous multi-carrier code division multiple access. The synchronization in uplink transmission can be maintained by using signaling to control it. The performance is evaluated compared with the asynchronous system. Numerical results show that our synchronous transmission technique can offer better performance than conventional asynchronous transmission, especially for an exponentially decaying multipath intensity profile.
