Abstract
In this paper, a measurement method for DTMB modulator which performs the estimation of timing and frequency offsets, channel impulse response (CIR), as well as modulation error ratio (MER) by using only two consecutive frames in an iterative manner is proposed to precisely measure the modulator performance in short time. Both simulation and lab testing results show that the measurement method could reflect the performance of DTMB modulator with high accuracy.
