With a very wide frequency band not allocated at present, THz waves have many optimal characteristics such as high transmission rate, large capacity, and high security. The research of THz communication technology has become a hotspot in wireless communication. For THz wireless communications, it is crucial to study advanced electrical signal processing techniques. In this paper, in view of the shortcomings of traditional orthogonal frequency division multiplexing (OFDM) technology, we propose wavelet transform orthogonal multicarrier modulation method in THz system. In addition, we study THz channel coding technology to ensure that the THz wireless communication baseband system has better bit error rate (BER) performance and low computational complexity. Based on above, a THz wireless communication baseband system is conceived.

基于小波变换的太赫兹无线通信系统

在目前尚未分配的非常宽的频带下，太赫兹波具有许多最佳特性，例如高传输速率，大容量和高安全性。太赫兹通信技术的研究已成为无线通信领域的热点。对于太赫兹无线通信，研究先进的电信号处理技术至关重要。针对传统正交频分复用技术的不足，提出了在太赫兹系统中的小波变换正交多载波调制方法。此外，我们研究了THz信道编码技术，以确保THz无线通信基带系统具有更好的误码率（BER）性能和较低的计算复杂度。基于以上，构想了太赫兹无线通信基带系统。
