A novel modulation scheme combining the advantages of CP-OFDM and TDS-OFDM
In this paper, a novel modulation scheme named time domain and frequency domain united orthogonal frequency division multiplexing (TFU-OFDM) is introduced. The main characteristic of TFU-OFDM is the joint time-frequency utilization of the pseudo-noise (PN) sequences as guard intervals in time domain and the inserted pilots in frequency domain. Simulation results and analysis show that compared with the cyclic prefixing orthogonal frequency division multiplexing (CP-OFDM) system, TFU-OFDM achieves faster and more reliable synchronization, and provides similar performance of channel estimation and equalization. On the other hand, compared with the time domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) system, TFU-OFDM provides the same synchronization performance, but the computational complexity of channel estimation and equalization is greatly reduced.
