Description: We compare the energy efficiency of some transmission
schemes in wireless sensor networks. By constraining
the system to end-to-end throughput requirements, we assume
that the nodes in multi-hop and cooperative schemes operate
at a spectral efficiency which is twice that of the single-hop
transmission. By taking into account the energy consumption of
the RF circuitry, we show that cooperation may be considerably
more energy efficient than non-cooperative schemes even in small
transmission ranges, specially if a feedback channel is available. Platform: |

Description: ALOHA协议的思想很简单，只要用户有数据要发送，就尽管让他们发送。当然，这样会产生冲突从而造成帧的破坏。但是，由于广播信道具有反馈性，因此发送方可以在发送数据的过程中进行冲突检测，将接收到的数据与缓冲区的数据进行比较，就可以知道数据帧是否遭到破坏。-ALOHA protocol s thought is very simple, as long as the user data to be sent, although let they send. There are, of course, such conflicts which cause the destruction of the frame. But, because the radio channel has feedback, so the sender can be tested to the conflict in the process of sending data, the received data comparison with data of the buffer, you can know whether data frame was damaged.

Description: 展示了线性、DFE、MLSE均衡器的信噪比性能，并通过蒙特卡罗模拟信道估计结果确定。-This demo shows the BER performance of linear, decision feedback (DFE), and maximum likelihood sequence estimation (MLSE) equalizers when operating in a static channel with a deep null. The MLSE equalizer is invoked first with perfect channel knowledge, then with an imperfect, although straightforward, channel estimation algorithm. The BER results are determined through Monte Carlo simulation. The demo shows how to use these equalizers seamlessly across multiple blocks of data, where equalizer state must be maintained between data blocks.

Description: 与在空间域上通过适当信号处理来分离多用户相比，下行多用户多输入多输出（MU-MIMO）传输技术因其显著增加系统容量的潜力近来已经得到广泛关注。令人遗憾的是，这些技术需要准确的信道状态信息保证其正常运行。然而在实践中，由于在FDD系统中反馈信道的有限容量导致精确的CSIT是难以获得的。本文研究的系统采用MU-MIMO下行链路传输中的分解有限反馈。特别是，支持能够处理用户间干扰的方案的必不可少的信息是确定的，根据把残余的用户间干扰功率最大限度地减小来设计最佳的码本。模拟结果表明，一般的有限反馈对通过MU-MIMO分解变速器获得的交互信号有显著的影响。-Abstract — Downlink multi-user multiple-input multiple-output
(MU-MIMO) transmission techniques have gained much attention
recently because of their potential to significantly increase system
capacity compared to single-user transmission by separating
multiple users in the space domain through appropriate signal
processing. Unfortunately, these techniques require accurate
channel state information at the transmitter (CSIT) for their
proper operation. In practice however perfect CSIT is hard to
obtain due to capacity-limited feedback channel in FDD systems
for example. In this paper we investigate systems employing
MU-MIMO decomposition transmission in the downlink with
limited feedback. In particular, the essential information that
enables the scheme to deal with inter-user interference is
identified and the optimal codebook design in terms of minimizing
the residual inter-user interference power is derived. Simulation
results show that in general limited feedback has a Platform: |

Description: CSI feedback allows downlink transmission
to be adaptively optimized based on the
instantaneous DL channel, so that closedloop
beamforming and adaptive link adaptation
can be enabled to optimize the system
performance. The DL reference signal used
for CSI measurement is different in Rel-8
and Rel-10. In Rel-8, CSI measurement is
based on CRS, which is also used for data
demodulation. In contrast, CSI measurement
in Rel-10 is based on a set of newly introduced
CSI-RS signals, which is low-dutycycle
and low-density, and allows a higher
reuse factor than Rel-8 CRS. Platform: |

Its purpose is to complement, not replace, Matlab's Image Processing Toolbox, and in fact it requires that the Matlab Image Toolbox be installed. Emphasis has been placed on code efficiency and code reuse. Thanks to everyone who has given me feedback - you've helped make this toolbox more useful and easier to use.(The toolbox is divided into 7 parts, arranged by directory:
channels Robust image features, including HOG, for fast object detection.
classify Fast clustering, random ferns, RBF functions, PCA, etc.
detector Aggregate Channel Features (ACF) object detection code.
filters Routines for filtering images.
images Routines for manipulating and displaying images.
