在计算机上产生一组实验数据,首先产生一段零均值白噪声数据u(n),令功率为 ,让u(n)通过一个三阶FIR:
得到y(n). .y(n)上加三个实正弦信号f1’=0.1,f2’=0.25,f3’=0.26调整 和正弦信号幅度信噪比大致为10dB,50dB,50dB. (1) 令N=256,描绘xn波形;
(2)得出真实功率谱密度 .
(3) 利用此实验数据Pisarenko谐波分解法估计该实验数据的正弦频率及幅度。
(On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)

Tues-A17_01-Beatty-Gridding
In this session, I will focus on the gridding method for fast image reconstruction from non-
Cartesian data [1-5]. While gridding is not the only game in town, it is the reconstruction of
choice when reconstruction time is an issue. Other reconstruction techniques include rBURS
[6] and non-Cartesian iterative methods [7,8]. Non-Cartesian iterative methods generally use
gridding and inverse gridding as their core operation, so even when gridding is not the right
solution for an application, an understanding of gridding can be useful.
I will cover the main steps of the gridding algorithm and then discuss some implementation tips
that can signicantly reduce the computation time. Finally, I will present some illustrations and
viewpoints that I have found to aid in an intuitive understanding of the gridding method, which
can be helpful when designing the density compensation function and judging the appropriateness
of gridding as a solution for a particular application.
