高效信道化接收机的信道动态重构技术

Channel Dynamic Reconstruction Technology of Efficient Channelized Receiver

对于分布在不同信道且信道个数动态变化的大宽带中频信号,往往采用多通道数字接收机,不仅实现复杂且效率低下。为了解决以上问题,提出了一种高效数字信道化接收机的信道动态重构技术。该技术能够检测到接收信号所占用的信道个数及位置,动态地配置原型综合滤波器以适应信号带宽,将分布在若干个连续信道的子信号重构还原为一个完整接收信号。通过仿真实验验证了提出的数字接收机结构的有效性和可行性。

For big wideband received signal distributed in different channels and the number of channels is random, the multiply channels receiver is always used. But the construction of multiply channels receiver is complex and the efficiency is low. An efficient dynamic digital channelized receiver based on a channel reconstruction technology is proposed. The number and the position of the channels can be detected so that the prototype synthesis filter is configured to adapt to the bandwidth dynamically. The subsignals in different channels can be reconstructed to a complete signal. The simulation experiments show the proposed algorithm is effective and feasible.
