Description: 本文主要研究了W-WAN中GPRS网络的移动视频传输问题。文中探讨了GPRS的网络结构、协议体系以及链路特性，从中我们看出：
GPRS网络链路不仅具有一般无线链路数据传输中遇到的延迟大、误码率高等共性问题，而且具有移动通信系统采用蜂窝频率复用方式带来的小区切换，
以及由于通信中链路性能随着地理位置变换而变化造成的GPRS网络中不可避免的经常性遭遇的冗长时延和突变时延。
这使得目前GPRS网络中使用的传统TCP或UDP传输协议均不能适应GPRS自身的链路特性，也不能实现高效的分组传输。-This paper mainly studied the W-WAN in the GPRS network for mobile video transmission problems. The article discusses the GPRS network architecture, protocol architecture, as well as link characteristics, from which we can see: GPRS network link not only has the general wireless link data transmission delay encountered in large, common problems of higher bit error rate, and with mobile communications system uses a cellular frequency reuse methods brought about by cell switching, as well as the communication link performance with the location change and change is inevitable GPRS network, the recurrent encountered lengthy delay and delay mutation. This makes the current GPRS network using the traditional TCP or UDP transport protocol are unable to adapt its own GPRS link characteristics, but also efficient packet transmission can not be achieved.

Description: 多径信道仿真
有三条固定路径的AWGN多径信道的QPSK系统进行BER性能方针，并与在理想的AWGN信道中同样系统的BER进行比较，为简化模型，作如下假设：
1，信道中有三条路径，包括一条没有衰落的LOS路径和两条具有瑞利衰落的路径。与各路径相应的接收功率以及路径间的延迟差是仿真的参数
2，信道的锐利衰落仅影响发送信号的幅度，不影响瞬时相位。
3，在符号间隔内各多径分量的衰减幅度是常数，并与相邻间隔无关。-Multipath channel simulation There are three fixed path multipath AWGN channel BER performance of QPSK systems approach, and in an ideal AWGN channel BER the same system for comparison, in order to simplify the model, make the following assumptions: 1, There are three channels path, including a no decline LOS path and the two have a Rayleigh fading path. Corresponding with the path to receive power as well as the path delay difference between the simulation parameters of 2, channel sharp decline affects only the magnitude of the transmitted signal, does not affect the instantaneous phase. 3, in the symbol intervals multipath component of the decay rate is constant, and has nothing to do with the next interval.

Description: Intelligent reflecting surface (IRS) is a promising
technology to enhance the coverage and performance of wireless
networks. We consider the application of IRS to non-orthogonal
multiple access (NOMA), where a base station transmits superposed signals to multiple users by the virtue of an IRS. The
performance of an IRS-assisted NOMA networks with imperfect
successive interference cancellation (ipSIC) and perfect successive
interference cancellation (pSIC) is investigated by invoking 1-
bit coding scheme. In particular, we derive new exact and
asymptotic expressions for both outage probability and ergodic
rate of the m-th user with ipSIC/pSIC. Based on analytical
results, the diversity order of the m-th user with pSIC is in
connection with the number of reflecting elements and channel
ordering. The high signal-to-noise radio (SNR) slope of ergodic
rate for the m-th user is obtained. The throughput and energy
efficiency of IRS-NOMA networks are discussed both in delaylimited and delay-tolerant transmission modes. Additionally, we
derive new exact expressions of outage probability and ergodic
rate for IRS-assisted orthogonal multiple access (IRS-OMA).
Numerical results are presented to substantiate our analyses and
demonstrate that: i) The outage behaviors of IRS-NOMA are
superior to that of IRS-OMA and relaying schemes; ii) The M-th
user has a larger ergodic rate than IRS-OMA and benchmarks.
However, the ergodic performance of the m-th user exceeds
relaying schemes in the low SNR regime; and iii) The IRS-assisted
NOMA networks have ability to achieve the enhanced energy
efficiency compared to conventional cooperative communications Platform: |
