Description: Inter-symbol interference if not taken care off may
cause severe error at the receiver and the detection of signal becomes
difficult. An adaptive equalizer employing Recursive Least Squares
algorithm can be a good compensation for the ISI problem. In this
paper performance of communication link in presence of Least Mean
Square and Recursive Least Squares equalizer algorithm is analyzed.
A Model of communication system having Quadrature amplitude
modulation and Rician fading channel is implemented using
MATLAB communication block set. Bit error rate and number of
errors is evaluated for RLS and LMS equalizer algorithm, due to
change in Signal to Noise Ratio (SNR) and fading component gain in
Rician fading Channel. Platform: |

Description: 手持式摄像机在使用时常常会受到使用者有意无意抖动的影响,从而影响成像效果，造成录制视频的不稳定及跳动问题，尤其是在使用者在一场景中特写或者跟踪某一具体目标时，使用者通常不能准确定位到或者估计出运动目标的位置，从而造成目标在视频中位置的不稳定，造成视频的主观效果变得不理想。
为了解决这一问题，我们需要设计一种算法来识别这种无意义的运动并设法通过补偿的方式来使得场景中的目标物体保持位置稳定的状态。
手持式摄像机捕获的视频通常都会受到抖动的影响，这严重的影响视频的主观效果。
这里提出的算法可以可靠的用于数字视频的去抖动。这个算法通过识别这些意外的抖动并且利用运动补偿的方法来获得一个较好的视频输出。
这个系统可以分为三个模块：（1）运动估计模块；（2）抖动识别模块；（3）运动补偿模块。

[1] F Vella, A Castorina, M Mancuso. Digital image stabilization by adaptive block motion vectors filtering, IEEE Transactions on Consumer Electronics, 2002-Handheld cameras are often used by the user intentionally or unintentionally, the influence of jitter affect the imaging results, resulting in instability and beat the problem of recording video, and especially in the user in a scene close-up or tracking a specific target,users often can not accurately navigate to estimate the location of the moving target, resulting in the subjective effects of target location of the instability in the video, resulting in video not ideal.
In order to solve this problem, we need to design an algorithm to identify such a meaningless exercise and try to make the object in the scene to keep the position stable state by way of compensation.
The handheld camera captured video usually subject to the influence of jitter, the subjective effect of which seriously affect the video.
The algorithm proposed here can be reliably used for digital video to jitter. This algorithm by identifying the jitter of these accidents and the use of motion compensation m Platform: |

Description: 运动补偿是一种描述相邻帧（相邻在这里表示在编码关系上相邻，在播放顺序上两帧未必相邻）差别的方法，具体来说是描述前面一帧（相邻在这里表示在编码关系上的前面，在播放顺序上未必在当前帧前面）的每个小块怎样移动到当前帧中的某个位置去。这种方法经常被视频压缩/视频编解码器用来减少视频序列中的空域冗余-The motion compensation is a description of the adjacent frame (adjacent represented here on the coding relationship adjacent two, on the playback sequence not necessarily adjacent) difference method, specifically the one described earlier (adjacent said herein the coding relationship in front of, on the playback sequence not necessarily how each small block in the current frame the front) to move to a location in the current frame to go. Such methods are often video compression/video codec used to reduce the redundancy of the airspace in the video sequence Platform: |
