Incremental-data stealth-transmission method in DSSS

Wireless Networks, 2021
A direct-sequence spread-spectrum (DSSS) signal has many advantages, such as low SNR and strong anti-jamming ability; thus, it is widely used in various military and civil communication systems. However, hiding and high-data-rate transmission technologies have become the key factors affecting the future applications of the existing DSSS. To solve these

Two-Dimensional Information Transmission Method in DSSS

Wireless Personal Communications, 2021
In this paper, a two-dimensional information transmission method based on k step-complex spread spectrum (KS-CSS) is proposed. The aim is to solve the contradiction between the bandwidth and processing gain of a traditional direct-sequence spread spectrum (DSSS) channel, and to achieve better system performance (such as by obtaining higher processing ...

A DSSS Receiver for Dual-Mode DSSS/OFDM Wireless LAN Systems

2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2006
This paper introduces a DSSS baseband receiver suitable for a dual mode DSSS/OFDM wireless LAN system. Packet synchroniser with a pair of ADCs with dynamic sampling is used for detecting both DSSS and OFDM packets. For differentially encoded symbols, frequency offset and phase offset can be compensated based on their inherent characteristics.
