应用于TTNT信号的树形信道化数字接收机
Tree Structure Channelized Digital Receiver for Tactical Targeting Networks Technology Signal
摘要
Abstract
The hopping frequency signals can be received accurately and efficiently by the channelized re-ceiver in the case that the frequency point parameters are determined.The tree structure receiver ensures the independence of the channel,and is flexible to apply.Then tree structure receiver is applied to the sig-nal reception of Tactical Targeting Networks Technology(TTNT) data link.The tree multi-level cascade structure receiver is designed for the TTNT signal which includes uniform distributed 16 hopping frequency points.The computation complexity of this structure is analyzed and the simulation results have proved the feasibility of the structure.Simulation results show that the tree multi-level cascade structure is efficient to separate the signals from different frequency points with the advantage of flexible structure and practicabili-ty,although the computation complexity of the tree multi-level cascade structure increases compared with that of the polyphase discrete Fourier transform(DFT) filter banks structure.关键词
