Abstract

Abstract

A cyclic autocorrelation algorithm of Time Division Data Modulation Binary Offset Carrier (TDDM- BOC) signal, based on frequency domain accumulation, is proposed to estimate the signal parameters: subcarrier rate, Pseudo Noise (PN) code rate and carrier in multipath fading channel. Firstly, the cyclic autocorrelation of received TDDM-BOC signal is computed, then frequency domain accumulation is used to reduce the influence of noise. Finally, through interval measurement between the peak pulses in different slices, parameters mentioned above can be estimated. Simulation results show that the proposed algorithm is effective and works well under the condition of low Signal-to-Noise Ratio (SNR), which has a certain reference value for Bei-dou navigation receiver design.
