Abstract :
In this paper, a measurement method for DTMB modulator is proposed, 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. Both simulation and lab testing results show that the measurement method could reflect the performance of DTMB modulator with high accuracy.
