代码说明:

  该代码是对人脸进行光照处理,先进行gamma变换,然后进行Dog双边滤波,然后进行灰度亮度的均衡。该方法能够有效提高光照变化的情况下的系统识别性能(The code is the human face of light treatment, the first for gamma conversion, and then Dog bilateral filtering, then the brightness of the gray balance. The method can effectively improve the illumination changes in the case of system identification performance)

    假设截获了一段短波数字通信的信号,要求解调出最终的信息,每组解调出来后,将10组信息组合起来,恢复最终的信源输出数据。 先验信息:两组数据文件,编号为1、2,每组I、Q两路存放,格式为“int16”,采样率为9600Sa/s,其中第一组为单径情况,第二组为多径情况。 参数符合MIL-STD-188-110A标准; 同步序列为syn=seq.dat,BPSK调制; 接收机频率稳定度高于1e-6。 文件中有效信息总长度为333.75s,其中同步头长为5/12s,每时隙1/6s,训练序列占10 ,在数据之前; 交织方式为全交织,矩阵交织,列为1000,在比特级进行; 纠错码码率为1/2; 调制方式为BPSK、QPSK和8PSK中的一种,映射方式为二进制,BPSK相位偏移为0,其余两种为 。 (Suppose intercepted signal for a period of short-wave digital communications requires final demodulated information after each demodulated, combining 10 group information, to restore the final output data source. Priori information: two sets of data file, numbered 1, 2, each I, Q two-way storage, the format is int16 , sampling rate 9600Sa/s, where the first group is a single path, the second group multipath situation.

  • stop-and-wait
    Stop-and-wait ARQ is a method used in telecommunications to send information between two connected devices. It ensures that information is not lost due to dropped packets and that packets are received in the correct order. It is the simplest kind of automatic repeat-request (ARQ) method. A stop-and-wait ARQ sender sends one frame at a time it is a special case of the general sliding window protocol with both transmit and receive window sizes equal to 1. After sending each frame, the sender doesn t send any further frames until it receives an acknowledgement (ACK) signal. After receiving a good frame, the receiver sends an ACK. If the ACK does not reach the sender before a certain time, known as the timeout, the sender sends the same frame again.
