进而通过matlab建立模型,验证了此方法,并对其中的几个参数进行了分析和讨论。 - 2 . based on watterson model , this paper concentrates on the realization of doppler shift and doppler spread based on dsp
2 .针对watterson信道模型,着重研究了多普勒频移与多普勒扩展在dsp中的实现方法。 - Real - time production of doppler shift with a minimum precision of 0 . 1 hz is realized by means of interpolation on the basis of lookup method ; simulation of doppler spread is realized by using the gaussian shaped fir filter and linear interpolation technique . 3
在查表法基础上结合内插技术,实现了最小精度为0 . 1hz的多普勒频移的实时产生;运用高斯型fir滤波器结合线性内插技术的方法,实现了多普勒扩展的仿真。 - Estimation of doppler spread width which is equal to the maximal doppler frequency is an important way to calculate the velocity of the mobile equipment . the ways of estimating the frequency offset and doppler spread width in wcdma system are studied in this paper
准确地估计频偏进而进行频偏补偿可以使基带处理时的信号更加准确;准确地估计移动台的最大多普勒频偏,可用于估计移动台速度,进而用于切换预测等。 - If the target has a radial acceleration , conventional 2d - fft based data processing method will lead to a doppler spread in doppler domain . the high resolution of doppler domain due to coherent integration no longer holds , which is very important in target detection of othr
常规的二维fft处理在处理机动目标时往往由于目标存在径向加速度而会在多普勒域造成多普勒扩展,从而无法应用相干积累带来的多普勒域的高分辨力完成对目标的检测。
