无人飞行器通信中联合信道估计和Turbo均衡
Joint Channel Estimation and Turbo Equalization for UAV Communication
摘要
Abstract
The Turbo equalization can effectively overcome multipath fading and eliminate Inter⁃Symbol⁃Interference ( ISI ) to improve receiver performance.In view of such characteristics as fast time⁃varying and multi⁃path of UAV data link channel,an iterative receive algorithm of joint channel estimation and Turbo equalization is proposed.The algorithm uses single carrier modulation,and elimi⁃nates ISI by the feedback soft information between channel estimation and Turbo equalization. The Matlab simulation results show that the proposed algorithm can significantly improve the BER performance through more than 2 iterations compared with traditional Turbo equalization algorithm based on single carrier frequency domain.关键词
