Research and implementation of 16QAM based on FPGA

摘要

Based on the digital bit synchronization technology, Compared the characteristic QPSK demodulation and QAM demodulation of signals, To improve Gardner algorithm and use the Matlab simulation. Designed based on the Gardner algorithm 16QAM baseband signal bit synchronization, and used Modelsim simulation analysis, Demodution the improved algorithm to achieve the desired results.
