摘　　要：研究Link-16信号在无线衰落信道下的传输性能,对于提升数据链的侦察与对抗能力具有重要意义。本文给出了Link-16脉冲信号波形在平坦Nakagami衰落信道下的误码率表达式,包括DS-MSK解调解扩性能、信道译码性能。计算机仿真表明,所给出的理论误码率公式与实际的Monte Carlo仿真结果一致。In this paper, we have a discuss of the Link-16 signal transmission performance over the wireless fading channel. It is important to scouting the Link signals and the confronting performance. And in this paper,we have found the expression for the Link-16 pulses signal waves over a slow, flat Nakagami fading channel.We also discuss the DS-MSK modulation and demodulation performance and channel coding performance. As a result, the Matlab simulation is consistent to the theoretical analysis of Link-16, by Monte Carlo simulation.
