Title: OFDM_in_well_logging Download
 Description: 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.
