The article is devoted to the study of the hardware description language (HDL)
implementation the cell search procedure for the initial initialization of user equipment in a …

Quadrature phase shift keying (QPSK) is a digital modulation technique that transmits data
at a constant frequency whilst varying the phases of the carrier signal. QPSK is one of the …

This paper is devoted to the study of the signal synchronization conditions in the 5G
downlink. A model of the physical layer of a downlink communication channel is considered …

为满足未来6G 星地一体化系统对正交频分复用(OFDM) 技术低峰均比(PAPR) 的需求,
首先提出一种将选择映射(SLM) 算法与多小波OFDM 技术相结合的算法, 但此算法降低PAPR …

Orthogonal Frequency Division Multiplexing (OFDM) is a widely used modulation technique,
but it has a high Peak-to-Average Power Ratio (PAPR), which can cause problems for power …

The Digital sub-band system is an indispensable technology for the development of modern
society, which has a wide range of applications. This work is particularly concerned with …

This paper presents an assessment the noise immunity of telecommunication systems. The
cause of interference is destabilizing factors-conversion of the sampling rate of signals in the …

This article is devoted to the study of a method for choosing the shape of orthogonal
frequency division multiplexing signals in selective fading conditions. The result obtained is …

In response to the inefficiency of power amplifier in conventional Orthogonal Frequency
