Efficient-QoS-Support-for-Secondary-Users-in-Cogn
- While the required reliability of the sensing process can be expressed in terms of rarely enough overlooking the PU, we assume that the proper QoS for the SU is given by maintaining — with a given confidence level — a minimum bandwidth availabili

- 利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。-Bilinear transformation method is used to design a cascade elli
Downlink-MIMO-in-LTE-Advanced-SU-MIMO-vs-MU-MIMO.
- CSI feedback allows downlink transmission to be adaptively optimized based on the instantaneous DL channel, so that closedloop beamforming and adaptive link adaptation can be enabled to optimize the system performance. The DL reference sign
MIMO-performance
- MU-MIMO is widely considered a key technology for system capacity improvement in modern wireless networks. In contrast to SU-MIMO, where the spatial multiplexing gain is confined to a single user, MU-MIMO allows multiple users to be co-sche
energy_2012_2_30_40107
- From the figure, we observe that the performance gap between ideal and realistic feedback is much more pronounced for MU-MIMO compared to SU-MIMO, which illustrates the increased sensitivity of MU-MIMO with respect to CSI accuracy. This is
22B_Throughput
- This paper illustrates the results of the throughput of Secondary User (SU) in cognitive radios under cooperative scenario with the use of evolutionary algorithms in the presence of additive white Gaussian (AWGN) noise. In this work, the performa
