基于OFDM调制方式下的协作分集方式性能仿真
The Simulation Study of the Cooperative Diversity Based on OFDM Modulation
摘要
Abstract
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.关键词
