The IJF-OQPSK modulation technique achieves good spectral efficiency in digital communication systems. In this paper, an improved modulation technique called Modified Intersymbol-Interference and Jitter Free OQPSK (MIJF-OQPSK) is presented. Comparing with IJF-OQPSK, the MIJF-OQPSK obtains more superior property: the power spectral roll-off out-of-band is lower than 15 dB; the envelope fluctuation of the modulated signal amplitude drops down to 1.3 dB; and the spectral spreading is smaller in hard-limited channels.< >
