摘要 协作分集在无线通信中应用极其广泛,正交频分复用技术(OFDM)鉴于自身优势,在系统的频谱利用率、功率利用率、系统复杂性等方面具有很强的竞争力.首先介绍了协作分集中的两种协作方式与OFDM系统框架,对比分析了解码转发与放大转发在实现各自转发上所具有的优缺点;对比分析了CRC编码OFDM系统与卷积码编码OFDM系统仿真性能,决定采用卷积码实现OFDM协作分集中解码转发法(decode and forward,DAF)的编解码,并对OFDM协作分集的两种协作方式进行了系统仿真.仿真结果表明,加入协作分集的OFDM系统,获得了显著的分集增益,系统性能得到提高. Cooperative diversity is widely used in wireless communication.On the other hand,orthogonal frequency division multiplexing（OFDM） is highly competitive due to its advantages in systematic spectral efficiency,power utilization and the systematic complexity.In this paper,two methods to realize cooperative diversity in OFDM systems and the frame of the OFDM are proposed;compared the CRC coding OFDM system with the convolutional coding OFDM system,and analyzed the performance of the CRC coding OFDM system and convolutional coding OFDM system,we decide to adopt the convolutional codes to achieve the DAF of the cooperative diversity.Two cooperative protocols in OFDM cooperative diversity system are simulated.As is showed in the simulation results,the performance of the OFDM system with the cooperative diversity accesses to a significant diversity gain.
