新的符号定时和载波频率同步算法
一种新的符号定时和载波频率同步算法,该算法将OFDM符号分成几部分。它使用相关性和积累在几个OFDM
符号获得估计函数。当部分的长度小于ISI自由地区,该算法可以识别它。然后估计的最优符号定时和载波频率偏移可以获得。计算机仿真结果表明,该算法不仅可以跟踪时变信道变化但也有较小的MSE比ML估计算法。(A new symbol timing and carrier frequency synchronization algorithm is presented and the algorithm divides the OFDM symbol into several parts. It uses correlation and accumulation in several OFDM
symbols to acquire estimation function. When the length of part is smaller than that of ISI free region , the algorithm can distinguish it. Then the estimation of optimal symbol timing and carrier frequency offset can be acquired .The computer simulation results show that the proposed algorithm not only can track time varying channel change but also has smaller MSE than that of ML
estimation algorithm.)

split-and-merge
segments image F by using a
split-and-merge approach based on quadtree decomposition. MINDIM
(a positive integer power of 2) specifies the minimum dimension
of the quadtree regions (subimages) allowed. If necessary, the
program pads the input image with zeros to the nearest square
size that is an integer power of 2. This guarantees that the
algorithm used in the quadtree decomposition will be able to
split the image down to blocks of size 1-by-1. The result is
cropped back to the original size of the input image.
