Description: 一个cdma2000的系统仿真器，附英文手册-The cdma2000-UV Simulator estimates the performance of data transmissions at the physical layer
of the mobile communications technology cdma2000 1X. These wireless data transmissions enable
the communication between mobile stations (e.g., cellular phones, PDAs, laptops) and base
stations (i.e., the communication systems that provide network access to the final user). Examples
of these transmissions include voice, e-mails, and text messages. The simulation results are
calculated according to the simulation parameters set by the user. For example, the user may set a
non-moving mobile station in an indoor environment or a moving mobile station in a vehicular
environment. With the results obtained with the simulator, the user can perform different analyses
such as the degradation in system performance due to an increase of the number of mobile stations
or the effects of multipath channels on CDMA transmissions. Also, the cdma2000-UV Simulator
assists the user in understanding the Platform: |

Description: THEORY OF
CODE DIVISION
MULTIPLE ACCESS
COMMUNICATION
The objective of this book is to provide an introduction to code division multipleaccess
(CDMA) communications. Our motivation for emphasizing CDMA communication
is a result of the technological developments that have occurred during
the past decade. We are currently witnessing an explosive growth in wireless
communication and cellular mobile radio systems, which are based on different
multiple-access techniques. We anticipate that, in the near future, we will see
a replacement of the current time- and frequency division methods in wireless
communication and mobile radio by CDMA.

Description: 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.

Description: 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。(With the great development of cellular mobile communication market, the next generation communication will be mobile multimedia communication.
This situation raises a problem of how to control the power of multimedia sources other than voice sources. In discussing this problem, we introduce mathematical models and concepts in microeconomics as well as game theory. In this paper, the quality of telephone calls is called "validity", and distributed power control for a CDMA telephone communication is regarded as a "non-cooperative game".) Platform: |
