Abstract

PURPOSE:To reduce the fading effect by transmitting the sample row adjacent to the sample row transmitted via the different burst signal and giving both interpolation and extrapolation to the samples erased at the recomposition time by the before and after sample value. CONSTITUTION:In the time-division communication system in which the transmission line receives the fading effect, the odd and even samples transmitted at the transmission side undergo the 2-phase modulation alternately in the form of the burst data and are then transmitted to be supplied to 2-phase modulated wave demodulator 400 through input terminal 601. Then the original burst data signal is delivered to terminal 600 after demodulation through demodulator 400. These signals are classified into the odd and even sample groups via pre-code detector 303 plus odd and even code detectors 304 and 305 to be supplied to odd and even shift registers 200-205 and 210-215 respectively. And the sample value of before and after the erased sample is interpolated and extrapolated through adders 250-252 and 260-262, 1/2-multiplication circuits 230-232 and 240-242 plus switches 270 and so on.
