Acquisition of $m$-Sequences Using Recursive Soft Sequential Estimation
Acquisition of $m$-Sequences Using Recursive Soft Sequential Estimation
A novel sequential estimation method is proposed for the initial synchronization of pseudonoise (PN) signals derived from m-sequences. This sequential estimation method is designed based on the principle of iterative soft-in-soft-out (SISO) decoding, and hence we refer to it as the Recursive Soft Sequential Estimation (RSSE) acquisition scheme. The RSSE acquisition scheme exhibits a complexity similar to that of a conventional m-sequence generator, which increases only linearly with the number of stages in the m-sequence generator. Furthermore, our simulation results show that the acquisition time of the proposed RSSE acquisition scheme is also linearly dependent on the number of stages in the m-sequence generator. Hence, the employment of the proposed RSSE acquisition scheme is beneficial for employment in the acquisition of long m-sequences.

Abstract
A novel sequential estimation method is proposed for the initial synchronization of pseudonoise (PN) signals derived from m-sequences. This sequential estimation method is designed based on the principle of iterative soft-in-soft-out (SISO) decoding, and hence we refer to it as the Recursive Soft Sequential Estimation (RSSE) acquisition scheme. The RSSE acquisition scheme exhibits a complexity similar to that of a conventional m-sequence generator, which increases only linearly with the number of stages in the m-sequence generator. Furthermore, our simulation results show that the acquisition time of the proposed RSSE acquisition scheme is also linearly dependent on the number of stages in the m-sequence generator. Hence, the employment of the proposed RSSE acquisition scheme is beneficial for employment in the acquisition of long m-sequences.
