Title Research and implementation of the matched filter receiver
Abstract
Matched filter receiver is the best receiver with maximum Signal to Noise Ratio (SNR) output, which is broadly used in digital wireless communication system and has a direct and significant influence on the performance of the whole system.
The development and application of MATLAB and FPGA technology greatly changed the implementation method of traditional digital system. MATLAB is an interactive environment and advanced language that allows programming, calculating and visualization. FPGA is a programmable logic device, of which Verilog HDL used in the paper is the programming Language. The procedural programming of Verilog is a great convenience for the designers.
The paper introduced the statistical model and the basic principle of the best receiver, analyzed the basic principle of the matched filter receiver, presented the implementation on matched filter receiver based on MATLAB. The key point of the paper focused on the design for matched filter receiver of QPSK signal based on Verilog HDL. The paper analyzed the algorithm and program of Verilog, and presented the simulation results based on Altera Quartus II. In addition, the paper proposed several optimization methods for matched filter, starting from the structural aspects of the matched filter for multipliers, shift registers and the overall structure. Depending on the actual application background, the relevant optimal design can provide some reference value.
