| Summary: | 碩士 === 國立交通大學 === 電信研究所 === 85 === In this thesis, we implement a 64-QAM IF transceiver based on
commercial chips, which work well in a cable modem system
experiment. In addition, we design a low phase noise RF
upconverter to upconvert the 43.75MHz IF 64-QAM signal to
450-750MHz band. The BER (Bit Error Rate) test results show that
the 64-QAM transmission system using our RF upconverter
encountered only 3dB power penalty at BER=1e-6 when comparing to
the theoretical limit.
