In this paper, we investigate the timing and carrier
frequency offset (CFO) synchronization problem in decode and
forward cooperative systems operating over frequency selective
channels. A training sequence which consists of one orthogonal
frequency-division multiplexing (OFDM) block having a tile
structure in the frequency domain is proposed to perform synchronization.
Timing offsets are estimated using correlation-type
algorithms. By inserting some null subcarriers in the proposed tile
structure, we propose a computationally efficient subspace decomposition-
based algorithm for CFO estimation. The issue of optimal
tile length is studied both theoretically and through simulations.
By judiciously designing the tile size of the pilot, the proposed
algorithms are shown to have better performance, in terms of
synchronization errors and bit error rate, than the time-division
multiplexing-based training method and the computationally demanding
space-alternating generalized expectation-maximization

SGALAB工具箱，最新beta5的，主要是刚才从pudn上下了一个垃圾工具箱，东西已经损损坏无法解压了。所以给大家传个新的，肯定能用(Toolbox SGALAB latest beta5, mainly just up and down from a garbage pudn Toolbox, things have been unable to extract a damage loss. So give us a new mass, be sure)

设计一个可以输入若干评委分数的表单，可以通过两个for循环分别找出分数的最大值和最小值，存入到两个变量，把评委的分数存入到一个数组中，计算时去掉找出的最大值和最小值即可得出最后得分。
(You can enter a number of judges to design a fractional form, you can find the maximum and minimum scores for each through two loops, credited to two variables, the judges scores deposited into an array, remove the calculation to find out the maximum and minimum values to arrive at a final score.)
