The UAV-mounted base station has been integrated into 5G and beyond to provide
communication in an emergency when conventional systems fail due to some reason …

A point-to-point (P2P) communication system based on the CPM-DSSS scheme ensures
reliability, security, and antijamming capabilities. However, for reliable detection of data …

Bit sign transitions cause significant attenuation of the correlation peak, thereby decreasing
the acquisition probability. Based on an analysis of the impact of bit sign transitions on …

This work contains a description of a multicast data transmission system that implements
multiple access mechanisms through code division of channels. An idea is put forward to …

Channel state information (CSI) is essential in a 5G wireless network since this information
has to be utilized while doing beamforming and equalization in a massive multiple-input …

This paper presents a low peak-to-average power ratio (PAPR) modulation scheme and
demodulation method for low-cost terminals in sixth-generation (6G), which is called one …

With the increasing demand of applications for the spread spectrum technique, especially
