[3G develop] CISQPSK DL : 0: 采用重要性采样的方法来代替蒙特卡罗仿真方法，确定数字通信系统的BER。重要性采样方法可以简单的增加信道噪声的方差，等效于使系统工作在一个较低的信噪比的环境下。-Using importance sampling method to replace the Monte Carlo simulation method to determine the digital communication system BER. Importance sampling method can be a simple increase in the variance of channel noise, is equivalent to make the system work in a lower signal to noise ratio environments.

[3G develop] quadra052 DL : 0: uadra is a web-gallery generator that runs in batch mode. It can also be used as a batch resize tool. It builds .html galleries and .jpg "contact-sheets" based on a list of input files. It can also be used simply as a batch image scaler cum jpg-converter, and be easily extended to do other operations on the given images as well. Both the file-list and the preferences can be saved in project files for multi-session work. Batch doesn t mean "unfriendly" so there is also a graphical interface. The projects can be saved for further editing. If you find yourself building often a lot of narrow-band multilingual .html galleries or if you are a photographer with loads of images to index-print or if you simply find yourself changing by hand image resolutions and compression quality then this tool might make your life a lot easier.

[3G develop] w-CDMa-3G-network DL : 0: The goal of this paper is to comprehensively review the handover policies in wideband code division multiple access (WCDMA) system. Mobile cellular communication becomes more and more important in today’s communication. In a cellular network, the radio and fixed links required are not permanently allocated for the duration of a call. Handover is the functionality to make an on-going call to a different channel or cell. It maintains a call in progress across cell boundaries in mobile communication. In order to provide a multitude of services, especially multimedia and high-bit-rate packet data. ETSI (European Telecommunications Standards Institute) adopted Wideband code division multiple access as the mainstream air interface solution for the third-generation networks.

[3G develop] TLM-2005-04-08_ori DL : 0: TLM 1.0 The files in this directory encapsulate the basic protocol for the user. They translate between user recognisable functions such as read() and write() to transport layer functions such as transport(). The user need never know about the implementation of the basic protocol. The definition of the basic protocol is in basic_protocol.h. There are two features which make this protocol "routable" : get_address() in basic_request and the default constructor in basic_reponse. basic_initiator_port is for code writers on the master side. It supplies convenient read/write functions to the basic protocol. basic_slave_base is the base class from which all basic protocol slaves should inherit. It implements transport(), unpacks the basic requests and responses, but leaves the read and write functions for the user to implement. -TLM 1.0 The files in this directory encapsulate the basic protocol for the user.

[3G develop] Report_Vinella_Polignano DL : 0: New generation mobile communication systems like Long Term Evolution (LTE) aim to deploy to customers a new mobile experience providing higher data rates and lower latencies that can make wireless devices a great platform to run a new whole set of services and applications, that was unimaginable just some years ago. However, the energy demands of battery powered devices, needed to support these new software applications substantially exceeds the capacity of the actual battery technology. The development of new architectures and procedures to build power-efficient and power-aware systems has become one of the main purposes in the design of new generation wireless networks.

[3G develop] bd_v312_setup DL : 0: 中的公式编写，并经过多次实例验证，与理论描述相符。文件包括两个m文件，一个是按模n展开，而另一个是逆变换，即按模n叠合。--unfolding of the tensor mode is a basic technology, there are a variety of code to make different result. However this code is written by referring to the authority of the tensor field of research literature Tensor Deco their positions and Applications and after several instances verification, is consistent with the theoretical description. The documents include two m-files, one is unfold.m, and the other is the inverse transformation, that is refold.m.
