Apparatus and method for increasing data transmission rate over wireless communication systems using spectral shaping

摘要: A system and method for reducing amplitude distortion in a data signal transmitted through cellular analog communication is embodied several forms. Each specific embodiment of the invention eliminates caused by clipping or sluggish recovery time induced limiter circuit which exists conventional systems. In one embodiment, pre-emphasis de-emphasis functions are offset complementary post-emphasis circuits so that high frequency components not clipped limiter. another bypassed selectively when transmitted. an alternative pilot tone combined with incoming signal. The characteristics such constant always sets gain limiter, thereby keeping constant.
