dc.description.abstract | This paper demonstrates the implementation of a space-frequency line coded-orthogonal frequency-division multiplexing (SFLC-OFDM) system. The SFLC-OFDM system utilizes downlink channel state information at the transmitter, which can be obtained from uplink channel estimation under channel reciprocity assumption between uplink-and-downlink channels. However, in practical implementations, channel reciprocity is violated due to the imperfect synchronization and radio frequency chain mismatch between transceivers. To recover the channel reciprocity, frequency-domain signal processing methods are proposed. Furthermore, a low computational complexity single-instruction multiple-data method is implemented to meet the time constraints in real-time operating systems. The experimental results demonstrate that channel reciprocity can be effectively recovered in the implemented SFLC-OFDM system, resulting in practical communication performance regarding the symbol error rate. | - |
