频谱感知中的能量感知算法，在不同虚警概率的情况下，信噪比和检测概率的变化。(In Cognitive Radio， spectru sensing is important。And energy detection is more. In different false alarm probability, the Pd vary with the SNR.)

This is a code for calculating PSNR of two images.

本算法描述了cdma反向信道的功率控制问题，包括基站以及移动台的功率控制以及相关的文章(description of the algorithm cdma reverse channel power control, , including base stations and mobile stations of the power control and the relevant article)

包括Matlab中的各种命令，便于大家查找。(The various commands, including Matlab, we find convenient.)

在OFDM系统 中，宽带信道被分割相互重叠的窄带子信道，如果各子信道 的带宽比信道的相干带宽要小，那么信号传输就有可能在无 频率选择性衰落或者平坦衰落的信道进行。(In OFDM system The wideband channel is divided into narrowband sub-overlapping, if each sub- The bandwidth is less than the coherence bandwidth of the channel, the signal transmission is possible without Frequency selective fading or flat fading channels.)
