wireless_1
- In this assignment, a report about Matlab functions of generating random numbers is prepared and then BPSK , QPSK and 8PSK symbols input sequence of bits are obtained. After that the expected value of generated symbols and the symbol energy are calcu
卫星通信中数字调相信号调制方式识别方法研究
- 针对数字卫星常用的 7 种通信信号调制方式(QPSK、8PSK、16QAM、32QAM、64QAM、16APSK、32APSK),对零中心归一化瞬时幅度谱密度最大值、四次方谱、幅度、高阶累积量四种特征参数进行了分析,提出了一种联合特征参数的信号调制识别方法.(Aiming at seven communication signal modulation modes commonly used in digital satellite (QPSK, 8PSK, 16QAM, 32QAM, 64QA
BPSK等仿真工具
- BPSK使用了基准的正弦波和相位反转的波浪,使一方为0,另一方为1,从而可以同时传送接受2值(1比特)的信息。由于最单纯的键控移相方式虽抗噪音较强但传送效率差,所以常常使用利用4个相位的QPSK和利用8个相位的8PSK。
