Abstract

For the problem of Time Division Data Modulation-Binary Offset Carrier (TDDM-BOC) modulation signal under low Signal-to-Noise Ratio (SNR), including blind estimation of the combination code sequence and information sequence, a revised method using Singular Value Decomposition (SVD) is proposed. Firstly, the received signal is divided into double-symbol-period-length temporal vectors, with one-symbol-period overlapping, accumulates of these vectors one by one to form the signal matrix. Then, an operation of SVD may be applied to the observation matrix, and the estimation of the combination code sequence is obtained based on the left singular vector. At the same time the information sequence can be estimated through the right singular vector. The simulation results show that the proposed method has accurate estimation performance for the signal at the low SNR. It has a certain reference value for engaging in satellite navigation receiver design.

Key words： Time Division Data Modulation-Binary Offset Carrier (TDDM-BOC) signal Combination code sequence Information sequence Singular Value Decomposition (SVD)
