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

This program uses the timers to trigger EDMA events. These events in turn
* trigger linked EDMA parameter tables to fill a ping pong buffer structure.
* Set a breakpoint on swiProcessFunc(int arg). Then open two memory windows.
* Use ping as the address for one memory window and pong for the other. Then
* run the application. You ll note that the program bounces between the ping
* and pong buffers filling each with a value that comes from the source. The
* source in this case is the SDRAM timer control register and it simulates
* input data(This program uses the timers to trigger EDMA events.

覆盖保存是WSN的一个基本质量要求。选择一个最佳的簇头，以满足长时间的监视区域的完全覆盖。使用覆盖意识的方法来选择簇头，而不是基于能量的方法，可以增加场景有效时间。(WSN coverage preservation is a basic quality requirements. Choose one of the best cluster head in order to meet long surveillance area completely covered. Awareness of the methods used to select the cover cluster head, rather than energy-based method, can increase the effective time of the scene.)
