N-continuous has been proved to be an effective and simple way in reducing the out-of-band power radiation of orthogonal frequency division multiplexing (OFDM) signals. However, it achieves sidelobes reduction at the cost of additional distortion to data signals and requires iterative processing to reverse the transmitter processing. In this paper, a novel iterative receiver is proposed to estimate...
Interleaver is very important to interleave-division multiple-access (IDMA) system for separating users. But most interleavers are designed for conventional IDMA detection. In this paper, an improved interleaver in downlink is proposed for orthogonal frequency division multiplexing interleave-division multiple-access (OFDM-IDMA) system in high speed circumstance. Simulation results show that compared...
One of the main drawbacks of partial transmit sequences (PTS ) scheme is the requirement of side information (SI) for phase recovering at the receiver end, which reduces the frequency efficiency as well as transmitting performance. In this paper, a blind PTS using partial phase recovering scheme without SI is proposed for pilot-aided OFDM systems. The proposed scheme exploits the relationship between...
