为了掌握基于椭圆球面波的非正弦通信短波信道误码率性能，比较不同通信体制短波信道误码率性能的优劣，对Watterson短波信道模型原理进行了分析，根据Watterson短波信道模型原理，结合基于椭圆球面波的非正弦通信特点，提出了基于椭圆球面波的非正弦通信短波信道仿真方法，并对短波信道误码率性能进行了仿真。理论分析和仿真结果表明，在不同的短波信道条件下，基于椭圆球面波的非正弦通信短波信道仿真方法都能有效反映短波信道对基于椭圆球面波的非正弦通信误码率性能的影响，基于椭圆球面波的非正弦通信短波信道误码率性能优于基于OFDM技术的通信。

In order to master performance of HF channel bit error rate（BER） of non-sinusoidal communi- cation based on prolate spheroidal wave functions（PSWF） and compare performance of HF channel BER in different communication systems, the principle of watterson HF channel model was analyzed. Accord- ing to the principle of watterson HF channel model combined features of non-sinusoidal communication based on PSWF, a simulation method of non-sinusoidal communication based on PSWF in HF channel was proposed, and performance of HF channel BER was simulated. Theoretical analysis and simulation results showed that in different HF channel conditions, the simulation method of non-sinusoidal communication based on PSWF can effectively reflect influence of HF channel over performance of BER of non-sinusoidal communication based on PSWF. The performance of HF channel BER of the non-sinusoidal communication based on PSWF is better than that of orthogonal frequency division multiplexing（OFDM） technology.
