现代世界对移动通信的需求日益增长，移动通信技术的用户也在快速增长。为了不间断的通信，数据传输速率应该是最大的。因此，光纤无线电系统和无线通信一起用于高速数据传输。这种组合将增加蜂窝基站动态变化并满足流量要求的容量。为了更好地理解 M 进制 PSK 系统，使用 Simulink 中的通信工具箱为 M=64 的 M 进制 PSK 设计了一个基于 Simulink 的仿真系统。在本文中，我们提出了 64 PSK 数字调制技术对于传输的适用性，并根据 BER、散点图和眼图等性能指标对结果进行了分析。
The demand of mobile communications in the modern world is increasing day by day and subscribers for the mobile communication technologies are growing rapidly. The data transfer rate should be maximum for uninterruptable communication .Therefore, the Radio over fiber system along with wireless communication, is used for the high speed data transfer. This combination will increase the capacity for the cellular base stations to change dynamically and meet the traffic requirements. To better understand the M-ary PSK system, a Simulink-based simulation system is designed for M-ary PSK for M=64 using communication toolbox in Simulink. In this paper we propose the suitability of 64 PSK Digital Modulation Technique for transmission and the results are analyzed on the basis of BER, scatter plot and eye diagram like performance measures.
