Estimation of Spreading Code in non-periodic Long-Code DSSS Signal

2021 Sixth International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2021
To estimate the spreading code of the non-periodic long-code DSSS (NPLC-DSSS) signal, this paper proposed a similarity reconstruction estimation method. the Coefficient of Similarity (CS) was used to reconstruct the periodicity of NPLC-DSSS signal. Then,

NBI mitigation in DSSS communications via block sparse Bayesian learning

Signal Processing, 2019
Narrowband interference (NBI) is a common interference pattern in direct-sequence spread-spectrum (DSSS) communications. NBI mitigation is a very important issue to ensure the effectiveness of DSSS communications.

Security Enhancement of Fix Chaotic-DSSS in WSNs

IEEE Communications Letters, 2018
The security of the physical layer promises to provide secrecy for wireless communication. The chaotic direct sequence spread spectrum (chaotic-DSSS) is one of the distinguished techniques for providing secrecy in wireless communication. However, conventional chaotic-DSSS requires chip synchronization which makes this system complex to implement in ...

Efficiently All-Digital Code Tracking for Band-Limited DSSS Systems

IEEE Communications Letters, 2023
In this letter, we have studied the all-digital code tracking problem for band-limited direct sequence spread spectrum (DSSS) systems. Band-limited DSSS systems have many advantages over rectangular-pulse DSSS systems.
