基于高斯脉冲的超短波电台波形设计研究

针对GMSK基带信号的特点,在未引入编码条件下将Viterbi算法的思想运用于超短波高斯波形的最大似然序列估计中,相比逐符号检测达到最佳检测性能,获得了相应地功率增益,并仿真了不同BT值、定时偏差和抽样点数的波形性能。仿真结果可为超短波通信子网物理层波形设计提供理论基础,有较大的工程参考价值。

Research of Waveform Design in VHF Radio Based on Gaussian Impulse

Without coding the paper introduces the thought of Viterbi algorithm to the maximum likelihood sequence estimation of gaussian waveform in VHF radio comparing to symbol-by-symbol detecting method.The paper simulates the waveform performance of different BT values and symbol timing offset and the number of sampling.With acquireing the best performance and relevant power gain,the simulation results could provide the engineering guidance and theoretic foundation of waveform design in physical layer of VHF radio.
