ijf怎么记

In MSK modulation, due to the discontinuous slope during the switch time of the phasic path, the dropping velocity of the modulation spectrum is affected, and IJF-OQPSK is introduced to solve the limitation, smooth the phasic path and improve the spectrum.

MSK调制技术中，由于其相位路径在转换时刻的斜率不连续，影响了已调信号频谱的衰减速度，针对这一缺陷引入IJF-OQPSK，使得相位路径平滑，频谱特性有所提高。

Especially we have researched the IJF-OQPSK modulation technique, and the performance of its inter-symbol interference and time jitter free, and its strongly resisting of spectral spreading.

特别研究了IJF&OQPSK在消除码间干扰和定时抖动方面的性能及其优良的旁瓣特性和抑制频谱扩展特性。

Simulation results show that with the non-linear constant phase path, spectral spreading has been resisted and the envelope fluctuation has been reduced by using the new IJF signals on the phase modulation technologies.

仿真结果表明：将其应用于相位调制技术后，相位路径非线性平滑连续，有效降低了调制起伏幅度，抑制了频谱扩展。
