Abstract :
According to the frame structure of CMMB, A method of pseudo-range measurement with the aid of disciplined sequences for CMMB is proposed on the basis of simulating frame synchronization, carrier synchronization and sampling clock synchronization. The method adopts the pseudo-random code tracking technique and implements pseudo-range measurement on CMMB system. The simulation results show that carrier frequency offset error is less than 1e-13 and the pseudo-range measurement error is less than 6 meters when the sampling rate is 60 MHz.
