论文摘要
本文主要讨论了三个基本的数字调制过程询问FSK,PSK。这些调制方案的特征是其传输符号,该符号由逐渐间隔间隔的一组离散值组成。针对特定应用程序的数字调制技术的选择不仅取决于带宽效率和实现复杂性,还取决于稍微(BER)和信号与噪声比的错误率。二进制调制方法使用两个级别的符号,并且可以轻松实施,提供良好的错误证明。 BER是一个关键参数,用于评估将信号数据从一个位置传输到另一个位置的系统。 SNR是信号和噪声功率相互比较的众所周知的衡量标准。它直接影响系统错误性能的可能性。在本文中,我们使用MATLAB实施了询问,FSK和PSK。余弦信号已被用作载波。在本文中,提出了对ASK的BER性能,FSK和PSK的比较探索,并提出了用于通道利用率的FSK和PSK,并通过AWGN通道对SNR进行了研究,作为参考因子。
This paper mainly discusses about three basic digital modulation process ASK, FSK, PSK. These modulation schemes can be characterized by their transmitted symbols which consist of a discrete set of values occurring at gradually spaced intervals. The selection of a digital modulation technique for a specific application depend not only the bandwidth efficiency and implementation complexity but also error rate occurred in a bit (BER) and signal to noise ratio. Binary modulation methods use two level symbols and are facile to implement, provide good error substantiation. BER is a key parameter that used for assessing systems that transmit signal data from one location to another. SNR is well known measure of how the signal and noise power compare against each other. It directly affects the probability of error performance of a system. In this paper, we have implemented ASK, FSK and PSK using MATLAB. Cosine signal has been used as a carrier wave. In this paper, a comparative exploration of BER performance of ASK, FSK and PSK for channel utilization is proposed and the investigation are carried out with SNR over AWGN channel as the reference factor.
