    • PURPOSE: A method for compensating Rayleigh fading using modified sinc interpolation is provided to apply a waiting factor calculated by a modified sinc interpolation algorithm to a single shock wave response function of a conventional sinc interpolation according to time sections, so as to improve estimate accuracy for a data symbol. So that a BER(Bit Error Rate) can be reduced and the performance of a receiving device can be improved by a fast hardware operation speed. CONSTITUTION: Voice signals from a microphone(11) are converted to electrical analog signals. The analog signals are converted to bit signals by an A/D converter(12). The bit signals are converted to parallel signals as many as M carriers through a serial-to-parallel converter(13). The M parallel signals are converted to one data symbol per bit by a 16-QAM(Quadrature Amplitude Modulation) symbol converter(14), and pilot symbols are inserted every symbol period. The M parallel data symbols, where the pilot symbols are inserted, are converted to pulse signals through a pulse shape filter(15). The pulse shaped parallel data symbols are allocated by M subcarrier modulators(16), and converted to subcarrier signals. The M subcarrier signals are converted to high frequency signals through a subcarrier modulator(17), and transmitted to a channel(20).
    • 目的:提供一种使用修正的sinc插值补偿瑞利衰落的方法,用于根据时间段将由修正的sinc插值算法计算的等待因子应用于常规sinc插值的单个激波响应函数,以便提高估计精度 一个数据符号。 这样可以降低BER(误码率),并且通过快速的硬件操作速度可以提高接收设备的性能。 构成:来自麦克风(11)的语音信号被转换为电模拟信号。 模拟信号由A / D转换器(12)转换成位信号。 通过串并转换器(13)将位信号转换为与M个载波一样多的并行信号。 M个并行信号通过16-QAM(正交幅度调制)符号转换器(14)被转换成每比特一个数据符号,并且每个符号周期插入导频符号。 插入导频符号的M个并行数据符号通过脉冲形状滤波器(15)转换成脉冲信号。 脉冲整形的并行数据符号由M个副载波调制器(16)分配,并被转换成副载波信号。 M个副载波信号通过副载波调制器(17)转换成高频信号,并发送到信道(20)。
