Generate a decrescente exponetial pulse

图像处理中几种lms滤波的matlab代码(several auto_adaptive filter s algorithms of lms on image processing,using matlab)

Source code to Generate Parity check matrix for 0.4 Code Rate for chinese Standard.

Implements 2D Gabor filter for images works on Matlab an image has to be first read and then converted as gray-scale before passing on to this function.

BPAdaboost，包括主程序，测试集等等(BPAdaboost, including the main program, test sets, etc.)

Make sure that calling a non-function global doesn t crash the system while building the IC for it.

802.11的OFDM系统方针程序，比较全面详细。(802.11 OFDM systems approach procedures, more comprehensive details.)

说明：  用Matlab产生随机拓扑图，优化并显示结果。(Matlab random topology map, optimization and display results.)

说明：  认知无线电技术的提出是为提高频谱利用率，而认知无线实现的关键技术是频谱感知，众所周知协作检测提高了衰落环境中认知用户系统检测的性能，该文章是基于协作检测提出新的检测方案，利用了双门限方法提高了系统性能，兼顾带宽有限和增强性能两个方面，是基于门限检测的协作检测性能优化的前提。对以后门限优化协作检测非常有用。(In this paper, we employ a double threshold method in energy detector to perform spectrum sensing, while a fusion center in the cognitive radio network collects the local decisions and observational values of the secondary users, and then makes the final decision to determine whether the primary user is absence or not. Simulation results will show that the spectrum sensing performance channels is improved significantly under the proposed scheme as opposed to the conventional method.)

单载波频域均衡的完全编码，包括了调制解调，独特字，传输模拟，信道估计，频域均衡器设计等等完全的理论。(Single-carrier frequency domain equalization, including modulation/demodulation, unique words, transmission simulation, channel estimation, frequency-domain-equalizer design, etc.)
