| Abstract: | MAC operation of the symbol data is the key to the design of adaptive blind equalizer.The core computing unit——high performance MAC unit with booth encoding are designed and optimized through FPGA.And simulation indicates that a favorably equalized effect could be achieved.The blind equalizer based on MAC could eliminate inter-symbol interference and identify 16QAM signal.This design is up to the desired result. |
