摘要
针对802.11a/g在室内无线音频传输上的应用,根据室内信道的特点,提出了一种利用训练序列和导频子载波等信息进行载波频偏估计、信道估计以及剩余相位跟踪的算法。该算法复杂度低、易于硬件实现。仿真结果表明其具有较好的性能。
The 802.11a/g can be used in indoor wireless audio transmission.According to the characteristics of indoor channel,an algorithm,which utilizes training sequence and pilot subcarriers,is proposed for carrier frequency offset estimation,channel estimation and residual phase tracking.The proposed algorithm is low-complexity and can be easily implemented in hardware.The simulations results also show that it has good performance.
