Non-orthogonal multiple access (NOMA) is a candidate technology for the 5th generation cellular networks to reduce the big gap between network capacity and fast growing traffic. It applies superposition coding in transmitters and successive interference cancellation at the receivers to cancel intra-cell interference. The same frequency resource can be allocated simultaneously to multiple intra-cell...
This paper considers the problem of uplink scheduling in wireless networks supporting successive interference cancellation (SIC) at the physical layer. By allowing concurrent interfering transmissions, SIC enables multi-packet reception at the receiver resulting in increased network throughput. Specifically, we consider maximum throughput scheduling and proportional fair scheduling problems and study...
In CDMA systems, turbo multi user detection for multiple access interference cancellation and channel decoding in CDMA systems has an exponentially growing complexity with number of users. In these systems, when bandwidth efficient modulations like M-ary PSK are used another exponential factor that is relates to the levels of modulation prohibitively increases the computational complexity of the receiver...
Very fast infrared (VFIr) was promoted by the IrDA for data rate of 16 Mb/s. VFIr adopts HHH (1,13) code (a kind of run length limited/RLL code) to avoid ISI problems. With the increase of data rate, the effect of component and channel induced inter-symbol interference (ISI) becomes more and more crucial and cannot be compensated easily only by HHH-code's property. In this paper, we examine several...
