摘要
为提高数字广播电视传输发射的质量,文中提出了一种全新的抗干扰无线传输发射技术。首先,对原始数字广播电视信号进行预处理,得到去噪后的信号。其次,计算抗干扰无线传输发射有效覆盖服务区,在此基础上,构建单点发射和接收的抗干扰无线传输链路模型。最后,进行信号接收与解调。实验结果表明,应用该方法后,无线传输误码率最高不超过1%,信号传输质量得到了显著提升。
To improve the quality of digital broadcasting and television transmission,a new anti-interference wireless transmission technology is proposed in this paper.Firstly,preprocess the original digital broadcasting and television signal to obtain a denoised signal.Secondly,calculate the effective coverage service area of anti-interference wireless transmission,and based on this,construct a single point transmission and reception anti-interference wireless transmission link model.Finally,perform signal reception and demodulation.The experimental results show that after applying the proposed method,the maximum wireless transmission error rate does not exceed 1%,and the signal transmission quality has been significantly improved.
