基于 OFDM的高速遥传电缆调制解调器设计 基于 OFDM的高速遥传电缆调制解调器设计-Abstract : In order to meet t he demand of high data volume for imaging tool s , a cable Modulator/ De2
modulator is investigated and developed since it is t he key to any high2speed cable t ransmission sys2
tem. The Modulator/ Demodulator adopt s OFDM (Ort hogonal Frequency Division Multiplexing) tech2
nology to solve t he antinomy between t he high2speed data t ransmission and t he limited cable band2
width. The principle of OFDM is int roduced fir st . Based on t he OFDM principle , architecture block
diagram and hardware block diagram of t he cable Modulator/ Demodulator are designed and are de2
scribed in detail . OFDM Modulation/ Demodulation flowchart is al so presented and elaborated. Field
test result s demonst rate t hat the cable Modulator/ Demodulator design is practical and feasible.
