Real-time video streaming over wireless links imposes strong demands on video codecs and quality of networks. Many measures are made to design proper routing protocols and channel assignments (CAs) for multi-channel multi-interface (MCMI) wireless networks, since it can provide higher performance than single channel. However, there still has not been a well-studied proposal to guarantee real-time...
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...
Peak-to-average power ratio (PAR) reduction and sidelobes suppression are two challenges in orthogonal frequency division multiplexing (OFDM) systems. Many methods have been proposed to reduce either PAR or out-of-band power. However, few have been reported for joint reduction for both of them in the literature so far. In this paper, serial peak cancellation for PAR reduction is combined with the...
To overcome the PAPR problem of conventional orthogonal frequency-division multiplexing (OFDM) system, a significant amount of methods have been proposed. However, there are few literatures considering the PAPR reduction for uplink orthogonal frequency division multiple access (OFDMA) system. In this paper, we focus on the PAPR reduction for random interleaved uplink OFDMA system. Firstly, the conventional...
