摘      要：To achieve real-time and high-speed communication between the surface and the bottom hole, acoustic communication along drill strings has become the most promising method for the efficient utilisation of oil fields. Vector orthogonal frequency division multiplexing (V-OFDM) is a general transmission scheme that has two special forms, orthogonal frequency division multiplexing and single carrier frequency domain equalisation. Owing to its flexibility regarding the size of the vector block, it can be adapted to meet different requirements. In this study, the authors first employ V-OFDM modulation in uplink and downlink acoustic communication. Aiming for mass-data transmission and a simple transmitter in the uplink, small-data transmission and a simple receiver in the downlink, and strong noise interference, they investigate the transmission performance with different synchronisation timing errors and detection schemes, zero-forcing and the minimum mean square error. Simulation and circuit test results are presented to demonstrate the effectiveness of the proposed different transmission schemes and the corresponding performance analysis.
