摘要:
在介绍正交频分复用(OFDM)多载波系统实现原理的基础上,针对多载波系统对同步比较敏感和大的峰均功率比(PAPR)两个问题,将多载波系统发送端的反傅立叶变换(IFFT)模块移至接收端,提出了一种基于OFDM系统信号处理方式的高速单载波系统实现方案.基于ITU M.1225信道A模型,选用BPSK,QPSK和16QAM等调制方式,根据下一代移动通信系统信息速率要求对提出的单载波系统进行了仿真.结果表明:该方案具有多载波系统的优点,同时又有效克服了多载波系统的不足.
Abstract:
The principle of OFDM multi-carrier system is firstly introduced. In order to solve the sensitivity to synchronization and large PAPR in multi-carrier system, the IFFT module in multi-carrier system transmitter is removed to the receiver and a high-speed single-carrier system scheme based on the SP method in OFDM system is proposed. According to the basic demand on the next generation mobile communication system, the proposed single-carrier system in ITU M.1225 A channel model by choosing BPSK, QPSK and 16QAM is simulated. Results indicate the proposed scheme keeps the advantages of multi-carrier system and overcomes the disadvantages of multi-carrier system.
