提出超宽带系统中同步和信道参数的新型估计算法.首先对接收信号进行傅立叶变换,由傅立叶变换系数构造两个矩阵,把信道时延估计转化成矩阵束的特征值求解问题.在求解出时延后再进一步求解信道参数.算法的最大特点是能得到多径时延和多径增益的闭式解,避免现有算法普遍存在的搜索和迭代求解.

A new algorithm for the joint synchronous and channel estimation of Ultra-Wide Band (UWB) systems is proposed, which provides closed-form estimate and therefore avoid the iterative approaches commonly applied in existing methods. The discrete Fourier transform is firstly applied to the received data and then two matrices are constructed from the Fourier coefficients. These two matrices form a matrix pencil and we show the generalized eigenvalues of the matrix pencil provides the estimates of the multipath delays. After the delays are estimated, the multipath gains can be estimated by solving a group of linear equations.
