摘　　要：针对非均匀多载波整体解调中的信道分路实现问题,基于完全重构调制滤波器组的优化结构,提出一种非均匀多载波信道分路技术的FPGA设计方法。相对于均匀多载波信道分路的局限性,使得非均匀分路技术能够更加灵活地适应系统需求且易于实现。对非均匀多载波信道分路技术中涉及到的分析和综合两部分模块的FPGA实现方法进行了详细阐述,给出了硬件占用资源情况和误码测试结果,实现了多载波速率混合信号的重构。In order to implement the channel separation in nonuniform multi-carrier integral demodulation,based on the optimization structure of modulated perfect reconstruction filter banks,an FPGA design method of nonuniform multi-carrier channel-separation technique is proposed.Compared with the limitations of uniform multi-carrier channel-separation technique,the FPGA design method of nonuniform multi-carrier channel-separation technique can be flexibly adaptable to the requirement of the system,and it is easily implemented.The FPGA implementation method of such two modules as analysis module and comprehensive module,which are involved in nonuniform multi-carrier channel-separation technique,is described in detail.The results of resource occupation and BER of hardware are given.Based on this design method,the reconstruction of multi-carrier signals is implemented.
