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

MRF-for-Vision-and-Image-Processing
计算机视觉大牛Andrew Blake著的书。
《视觉和图像处理中的马尔科夫随机场》
Markov random fields for vision and image processing(This book sets out to demonstrate the power of the Markov random field (MRF) in vision.It treats the MRF both as a tool for modeling image data and, coupled with a set of recently
developed algorithms, as a means of making inferences about images. The inferences concern underlying image and scene structure to solve problems such as image reconstruction,
image segmentation, 3D vision, and object labeling. This chapter is designed to present some of the main concepts used in MRFs, both as a taster and as a gateway to the more
detailed chapters that follow, as well as a stand-alone introduction to MRFs.)

papr-pour-ofdm
In this section, the PAPR performance of the proposed
algorithms is shown. To evaluate the PAPR performance, the
CCDF is employed. The specification detail of simulation
parameters is given in TABLE I.
In Fig. 5 is shown the PAPR with a PTS method (U = 8) and
conventional PTS (U = 4) are improved 4.3 dB and 2.6 dB
from ordinary MIMO-OFDM signal when CCDF = 10− 4
respectively and Fig. 6 is shown the PAPR with an optimal
PTS method in case of 128 subcarriers.
