| 摘 要： | 在M.1225车速120km/h信道模型下,根据移动WiMAX的移动性和前导码的结构特点,利用非零导频子载波进行信道估计。探讨了2种信道估计算法和3种插值技术,并对其中的Cubic插值技术进行改进以降低计算复杂度。经仿真发现利用LS算法和Cubic简化插值技术进行信道估计能很好地实现性能与复杂度的折中,在实际系统中可获得满意的BER性能。

| Abstract: | The non-zero pilot sub-carriers were used to estimate channel response curve under the M.1225 Vehicular Test A channel model according to the mobility and preamble structure of the mobile WiMAX.Two channel estimation algorithms and three channel interpolation technologies were discussed.And the traditional cubic interpolation technology was simplified to reduce the system complexity.The simulation discovers that using the LS algorithm and the simplified cubic interpolation technology to estimate channel can... |
