摘要

基于变分演算的方法，解决了数字符号在选频信道上传输的预强调有限信号基的合成问题。研究表明，这种基在通信系统中的形成和应用归结为信号符号的自适应信道预编码，该预编码考虑了当前的信道选择并允许补偿码间干扰。计算实验结果证实了最优信号基的良好性能。

Synthesis of preemphasis finite signal bases for reduction of intersymbol interference

Based on the method of variational calculus is solved the problem of synthesis of preemphasis finite signal bases for transmission of digital symbols over frequency-selective channel. It is shown that the formation and application of such bases in telecommunication systems comes down to adaptive channel precoding of signal symbols, which takes into account the current channel options and allows to compensate the intersymbol interference. The results of computational experiment confirming the good properties of optimal signal bases.
