Increasing the symbol rate in QAM system using a new set of orthonormal basics functions

Journal of Electrical Systems and Information Technology, 2018
This paper proposes a new technique to increase the symbol rate in Quadrature Amplitude Modulation (QAM) using a new set of orthonormal functions. The proposed technique increases the rate of QAM symbols without increasing the bandwidth of the modulated ...

Modeling and analysis of inter-symbol interference (ISI) jitter

IEICE Electronics Express, 2007
This paper presents a novel modeling and analysis of inter-symbol interference (ISI)jitter in serial data channels either between chips or on chip. The simulation results show that ISI jitter is dependent on pole location, settling time, and damping ratio of the data serial channel.

Channel estimation of UFMC system in multipath channel

Dianxin kexue, 2018
As a candidate waveform of 5G,universal filter multi-carrier (UFMC) technology could inhibit out-of-band radiation,achieve loose synchronization and well support the short bursts of things in the transmission.However,in the UFMC transmission without ...

Equalization and Coding Techniques for Edge Modulation Signaling

IEEE Open Journal of Circuits and Systems
This paper describes equalization, coding, and crosstalk reduction techniques for edge modulation signaling. We analyze the inter-symbol interference of edge modulation using enumeration method and present expressions for the error rate from inter-edge ...

A low-complexity eigenvalue decomposition based-GFDM transceiver for self-interference elimination in next-generation wireless systems

Journal of Information and Telecommunication
Generalized Frequency Division Multiplexing (GFDM) is a flexible multi-carrier scheme and has a potential to overcome some of the limitations of orthogonal frequency division multiplexing (OFDM) specifically for diverse use cases of beyond 5G (B5G)/ 6G ...

Differential Faster-Than-Nyquist Signaling

IEEE Access, 2018
In this paper, we propose a novel differential faster-than-Nyquist (DFTN) signaling concept that allows us to dispense with any channel estimation at the receiver, while benefiting from a rate boost specific to faster-than-Nyquist (FTN) signaling.

Channel estimation for OFDM system based on deep learning

Tongxin xuebao, 2023
An efficient channel estimation model based on deep learning was proposed for the problems of inter-carrier interference and inter-symbol interference in 5G system signal reception.The estimated channels were obtained through a preliminary estimation at ...
