摘要
针对基于OFDM和智能天线的舰船无线通信环境,分析了现有OFDM系统中的智能天线波束形成算法,提出了一种新的最小二乘恒模算法应用于OFDM波束形成中的方案,并且引入了半盲自适应均衡,以降低信道特性对系统性能的影响,提出的算法能够在简化系统计算量的同时降低系统误码率。
In view of shipboard communication based on OFDM and smart antenna, current beamforming algorithms in OFDM system are analyzed. An improved scheme based on Least Squares Const Modulus Algorithm is proposed, and semi-blind channel equalization is included to decrease the influence of channel property. The proposed algorithm decreases the calculating complexity and bit error rate of the system.
