vi2
This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet.
For eg:-wavelets can be haar, db1, db2,dmey...............
Decomposition can be viewed in figure.
(Please note that select 256X256 image for better result.)
Then compression can performed,
PERFL2 give compression score.
Then reconstruction can be performed.
Each decompsition we can choose different threshold values.
For each threshold value we can calculate mse,psnr,pq(picture quality),
bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.

PowerControlforWirelessData
随着蜂窝移动通信市场的巨大发展，下一代通信将是移动多媒体通信。这种情况产生了一个问题，如何对语音信源以外的多媒体信源进行功率控制。在探讨这个问题上，我们引入微观经济学中的数学模型和概念以及博弈论理论。在本文中，电话的通话质量被称为“效度”，对于一个CDMA电话通信的分布式功率控制被看作是一个‘非协作的博弈’。(CDMA mobile communication system is a technology which will be used in the next-generation communications system, so wideband CDMA technology has been unprecedented attention, and a large number of improved algorithm to improve the performance of CDMA system has emerged in its various research on key technologies.)
