摘要
针对无线突发通信的特点提出了一种适用于无线突发通信的帧结构,并通过此帧结构利用最大似然法进行信道参数估计。通过选择参与运算的信道长度,仅利用加法及移位运算实现矩阵的相乘及求逆,可以在FPGA上实现信道参数的无偏估计。
A frame structure suitable for wireless burst communication is presented in this paper and channel parameters are estimated by maximum likelihood method using this structure.By selecting channel length in operation process properly,matrix multiplication and inversion could be calculated by addition and shift,which makes channel unbiased estimation is easy to be realized on FPGA.
