Description: Capacity of CDMA system depends on
an interference level in the system. There are therefore
RRM (Radio Resources Management) functions, which are
responsible for supplying optimum coverage, ensuring efficient
use of physical resources and providing the maximum planned
capacity. A call admission control algorithm based on load
factor evaluation and a fuzzy logic based call admission
control algorithm are presented and mutually compared in this
contribution

Description: RAKE技术与CDMA系统相结合,能够带来系统容量和通信质量的极大提
高。根据军事通信中对设备便携性及低功耗的特殊要求,本文研究了一种便携式
基站的收发系统,重点研究了其中的RAKE接收部分。给出了系统的发送方案和
接收方案,对接收机部分所涉及的关键技术和算法,包括数字下变频技术、匹配相关技术、多径搜索技术、信道估计技术、解调及多径合并技术进行了较为详细的分析和说明。在此基础上,运用VHDL语言进行了硬件平台上FPGA部分的功能实现,并对整个系统进行了调试,给出了一些相关的仿真及测试结果。最后对该系统还需进一步研究的问题进行了简要的介绍,对调试过程中的出现的一些问题进行了简单的分析和小结。
-CDMA system with RAKE combining technology, can bring the system capacity and communication quality significantly raised
High. According to military communications equipment portability and low power consumption special requirements, this paper, a portable
The base station transceiver system, which focuses on the RAKE receiving part. Then the system sends the program and
Receiving scheme, the receiver part of the key technologies involved and algorithms, including digital down-conversion technology, matching the relevant technology, multi-path search and channel estimation, demodulation and multi-path merging techniques on a more detailed analysis and explanation. On this basis, the use of VHDL, FPGA hardware platform to achieve some functionality, and debugging the system, given some of the relevant simulation and test results. Finally the system need further study are briefly introduced, and the emergence of the process of debugging some problems in a simple analysis and summar
