摘要:
将几种常用数字波形的陈-Mbius逆变换作为四路载波数字通信系统数字输入信号的编码波形函数族,由其对二进制输入信号进行调制后,直接叠加在一个物理信道上进行传输.在接收端,用与各调制编码波形对应正交的数字波形对各路信号进行同步相干解调,从而构成新的相干调制解调系统.应用MATLAB平台对系统进行性能仿真,并与传统的相干调制解调系统的仿真结果相比较.结果表明,该系统具有更优异的抗强噪声与抗干扰的性能,可实现多路载波数字通信的直接叠加,大大节省系统的初始投资与运行费用.
Abstract:
The Chen-Mbius inverse transform function set of the digital waveform is used as the code waveform function set of the input digital signal in the four-carriers digital communication system and the input binary digital signals modulated by each carrier are directly added together and transmitted through a physical line.At the receiving end,the digital waveforms respectively orthogonal to the corresponding code waveforms are used to coherently demodulate the signals on each carrier.These two orthogonal function set constitute the new coherent modem set-pair.Then the new type four-carrier digital communication system performance is simulated by the MATLAB platform and compared with the simulation result of the traditional system.The results of the comparison show that the new system has much more excellent performances to resist the strong noise and interference and the directly added multi-carriers digital communication could be realized and the system initial investment and the operation cost could be greatly saved.
