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

deriv
This function returns the numerical derivative of an analytic function.
Of special note, is the incorporation of the "complex stepderivative"approach which offers greatly improved derivative accuracy compared to approximations. This is especially germain when accuracy at the level of machine precision is a concern.

MATLAB视频图像考勤系统
说明： MATLAB视频图像考勤系统
该课题为基于MATLAB的摄像头的图像考勤系统。调用笔记本自带摄像头，从左侧进入为正1，右侧出去为负1，每统计到一个人数记为正负1.点击开始和点击结束为一个周期。带GUI界面。另外可定制二次开发基于图像的人数考勤系统。(Matlab video image attendance system
The subject is the image attendance system of camera based on MATLAB. Call the camera equipped with the notebook, enter from the left as positive 1, exit from the right as negative 1, and record the number of each person counted as plus or minus 1. Click start and click end as a cycle. With GUI interface. In addition, it can customize the secondary development of image-based attendance system.)
