Abstract

Generalized Frequency Division Multiplexing (GFDM) is a flexible multicarrier modulation scheme tailored to meet the diverse requirements of 5G and beyond (B5G) wireless systems. It provides flexibility to select subsymbols, subcarriers, and pulse-shaping filters, making it suitable for various B5G communication needs. Moreover, GFDM includes orthogonal frequency division multiplexing (OFDM) and single carrier frequency domain equalization (SC-FDE) as special cases. Since fading conditions greatly affect communication reliability, this paper derives a closed-form expression for the symbol error probability/symbol error rate (SEP/SER) of GFDM using M-QAM and M-PSK in generalized

α - κ - μ

fading channels. The study examines how fading parameters (

α, κ, μ

), pulse-shaping filters, roll-off factor, and subsymbol count influence SER performance. Results show these factors have a significant impact on error probability. This comprehensive analysis provides important insights for evaluating GFDM performance under complex fading scenarios, making it a valuable reference for GFDM system design for B5G wireless applications.

广义α−κ−μ信道下GFDM的符号错误概率分析：基于概率密度函数的超5G无线应用方法

通用频分复用（GFDM）是一种灵活的多载波调制方案，专为满足5G及以上（B5G）无线系统的各种需求而量身定制。它提供了选择子符号、子载波和脉冲整形滤波器的灵活性，使其适合各种B5G通信需求。此外，GFDM还包括正交频分复用（OFDM）和单载波频域均衡（SC-FDE）作为特例。由于衰落条件对通信可靠性的影响很大，本文推导了广义α−κ−μ衰落信道中使用M-QAM和M-PSK的GFDM的符号误码率/符号误码率（SEP/SER）的封闭表达式。研究考察了衰落参数（α、κ、μ）、脉冲整形滤波器、滚降因子和子符号计数对SER性能的影响。结果表明，这些因素对误差概率有显著影响。该综合分析为评估复杂衰落场景下GFDM的性能提供了重要见解，为B5G无线应用的GFDM系统设计提供了有价值的参考。
