Abstract

Wavelets have been applied in wireless communication systems in source and channel coding and transceivers design. This article proposes a new multi-carrier modulation approach to use Haar and Daubechies (Db2) wavelet-based stationary wavelet transform (SWT) in place of FFT because of no cyclic prefix, high spectral efficiency, less bandwidth usage, and its performance comparison of conventional transforms techniques such as FFT, DWT with SWT in an OFDM transceiver for Long term Evolution (LTE) in Stanford University Interim (SUI) channel models with zero-forcing equalization technique in the receiver section. The proposed system was tested with different modulation constellations such as PSK, QPSK, 64, and 128-QAM with 3GPP specifications for two users with user equipment data, ETU parameters (Extended typical urban) ETU-70 Hz, and calculated the BER. In SUI channels, 3dB of gain is improved in terms of energy per bit to noise ratio

斯坦福大学过渡信道中基于DWT、Haar变换和奇异小波分解的LTE-OFDM误码率分析

小波在无线通信系统的信源、信道编码和收发器设计中得到了广泛的应用。本文提出了一种新的多载波调制方法，使用Haar和Daubechies (Db2)基于小波的平稳小波变换(SWT)来代替FFT，因为它没有循环前缀，频谱效率高，带宽使用少，并且它与传统变换技术(如FFT)的性能比较。在斯坦福大学临时(SUI)信道模型中，采用零强制均衡技术的OFDM收发器中用于长期演进(LTE)的DWT和SWT。利用用户设备数据、扩展典型城市ETU参数(Extended typical urban) ETU-70 Hz，采用3GPP规格的PSK、QPSK、64和128-QAM等不同调制星座对系统进行了测试，并计算了误码率。在SUI通道中，3dB的增益在每比特能量与噪声比方面得到了提高
