摘要 针对电气与电子工程师协会802.11正交频分复用通信系统研究了一种从导频做采样频率同步和剩余相位跟踪的角度去分析导频位置的方法,该方法利用导频间隔对导频位置进行了优化。在电气与电子工程师协会802.11标准规定的帧格式基础上,利用数值仿真方法对提出方法所确定的导频位置和所提出的频偏估计补偿算法进行了性能分析。数值仿真结果表明,所提出的导频位置确定方法和频偏估计和补偿算法,在不提高系统复杂度的情况下,所提算法能够显著改善系统性能。 This paper studies a method of using pilot to do sampling frequency synchronization and residual phase tracking to optimize pilot location for IEEE 802.11 OFDM system, which is considered in the respect of using pilot interval. Based on the IEEE 802.11 standard frame format, using the method of numerical simulation method to make performance analysis of the identified position of pilot and frequency offset estimation compensation algorithm. Numerical simulation results show that the proposed method of optimizing pilot location and frequency offset estimation and compensation algorithm, under the condition of without raising system complexity, can significantly improve the system performance.
