摘　　要：以TCM编码和OFDM调制相结合的编码调制方法为基础,提出一种适用于成像测井高速通信系统的调制解调器设计方案,利用双路并传上行数据传输可达1.15Mbps,并用FPGA实现了井下调制器、DSP实现了地面解调器,通过对调制解调器的室内测试验证,该方案对提高成像测井系统的数据传输速率有效可行。A new design method for imaging logging system is proposed based on TCM encoding and OFDM modulating Techniques. The up-transmitting data rate is 1.15Mbps with double channels. The modem by FPGA and DSP is implemented. It has been proved that this method is practical and feasible in increasing the data transmission rate by test results.
