—In the K-user single-input single-output (SISO) frequency-selective fading interference channel, it is shown that the maximal achievable multiplexing gain is almost surely K/2 by using interference alignment (IA). However, when the signaling dimensions are limited, allocating all the resources to all users simultaneously is not optimal. So, a group based(More)
— In this paper we proposed two threshold-aided adaptive opportunistic transmission strategies in multiuser multiple-input multiple-output (MU-MIMO) downlink with limited feedback. Threshold scheme in company with transmission mode adaptation are employed to handle feedback cost and improve system performance. In one time slot, each mobile station (MS)(More)
—Topology control via per-node transmission power adjustment has been shown effective in extending network lifetime. However, most of existing algorithms construct static topologies which fail to consider the residual energy of network nodes, thus in fact they can not balance energy consumption efficiently. To address this problem, a lightweight distributed(More)
In additive white gaussian noise (AWGN) channel, chaos has been proved to be optimal coherent communication waveform in the sense of maximizing the signal-to-noise ratio (SNR). Recently, Lya-punov exponent spectrum of the chaotic signals after being transmitted through a wireless channel has also been proved to be unaltered, which paves the way for wireless(More)
