A-survey-of-spectrum-sensing-algorithms-for-cogni
The spectrum sensing problem has gained new
aspects with cognitive radio and opportunistic spectrum access
concepts. It is one of the most challenging issues in cognitive
radio systems. In this paper, a survey of spectrum sensing
methodologies for cognitive radio is presented. Various aspects
of spectrum sensing problem are studied from a cognitive radio
perspective and multi-dimensional spectrum sensing concept is
introduced. Challenges associated with spectrum sensing are
given and enabling spectrum sensing methods are reviewed.
The paper explains the cooperative sensing concept and its
various forms. External sensing algorithms and other alternative
sensing methods are discussed. Furthermore, statistical modeling
of network traffic and utilization of these models for prediction
of primary user behavior is studied. Finally, sensing features of
some current wireless standards are given.

PowerControlinWireles
本文提出一种联合盲自适应梯度算法的功率控制算法,该算法同时对功率向量和接收滤波器权向量进行迭代更新。仿真结果表明,采用本文提出
的功率控制算法, 在系统内用户发射总功率一定的条件下, 可以获得更高的用户信干比和更大的系统容量。(Throughout the monograph, we highlight the use of mathematical
language and tools in the study of power control, including optimiza-
tion theory, control theory, game theory, and linear algebra. Practical
implementations of some of the algorithms in operational networks are
discussed in the concluding chapter. As illustrated by the open prob-
lems presented at the end of most chapters, in the area of power control
in cellular networks, there are still many under-explored directions and
unresolved issues that remain theoretically challenging and practically
important.)
