各种最小二乘法汇总（算例及MATLAB程序）

现代通信系统要求通信距离远、通信容量大、传输质量好。作为其关键技术之一的调制解调技术一直是人们研究的一 个重要方向。讨论和仿真实现了基于FPGA的数字化DPSK调制解调系统。用Altera公司的FPGA开发平台Quartus II 3.0实现了一 个对基带信号的DPSK调制解调系统模型的仿真。(Modern communication systems require communication distance, communication capacity, transmission quality. As part of its one of the key technologies of modem technology is that people have been an important direction of research. Discussion and simulation of FPGA-based digital DPSK modulation and demodulation system. FPGA using Altera)
