- W4387029494 abstract "The article is devoted to the topical issue of creating a high-performance VLSI architecture for advanced QPSK modems. The QPSK modulation scheme is used in VLSI architecture for many high-speed applications such as satellite communications. VLSI is a technology by which 10,000-1 million transistors can be manufactured on a single chip. Since there was a need for additional functions of electronic devices, the development of NVIS technology improved. The proposed architecture is modeled in XILINX software. This software product is specialized tools for programming programmable logic devices in hardware description languages. The main goal of the research is to create a high-performance QPSK module, thanks to which it supports satellite communication with high bandwidth and energy efficiency. A QPSK modulator is a binary (base 2) signal that produces four different sets of input combinations: 00, 01, 10, and 11. Therefore, with QPSK, binary input combinations are combined from two bits. In the proposed project, 8-PSK and 16-PSK modulation with the basics of QPSK modulation and demodulation system were analyzed and modeled to obtain the required output. VERILOG coding was used for program simulation. Verilog is a hardware description language (HDL) used to model electronic systems. Verilog can run on both Windows 7, 8 and Windows 10 operating systems. Errors are coded and checked using XILINX software. This project is implemented to create high performance in NVIS using QPSK, 8-PSK, 16-PSK systems used for satellite communication. Implementing this process in any other module is easy, but in NVIS it is a big challenge." @default.
