In this paper, we consider a wireless network with one full-duplex (FD) base station (BS) and a set of half-duplex (HD) user equipments (UEs). In such scenario, in addition to the self-interference, the co-channel interference from uplink UEs to downlink UEs is the main bottleneck for the network performance. To overcome this, we consider the problem of maximizing the minimum fairness rate among all...
This paper considers an energy-efficient packet scheduling problem over quasi-static block fading channels. The goal is to minimize the total energy for transmitting a sequence of data packets under the first-in-first-out rule and strict delay constraints. Conventionally, such a design problem is studied under the assumption that the packet transmission rate can be characterized by the classical Shannon...
In the presence of narrowband interference, non-Wiener effects have been observed for the normalized least-mean-square (NLMS) algorithm and the affine projection algorithm (APA). The convergence performance of the affine projection algorithm (APA) is analyzed in the presence of strong narrowband interference. Firstly, the relationship between the APA and the NLMS algorithm is derived, with the help...
Carrier frequency offset (CFO) between transmitter and receiver carrier generators degrade the performance of adaptive filters seriously, even for very small CFO. Tracking analysis of the affine projection filter is carried out in the presence of CFO. The energy conservation relation of the affine projection filter with both random and cyclic nonstationarities is derived. Based on the energy conservation...
In this article, we propose an improved algorithm of blind signal separation that jointly exploits the selection of rational nonlinear functions and quasi-Newton method. The proposed algorithm uses rational nonlinear functions in constructing the cost function, which have less computational complexity than the usual nonlinear functions such as hyperbolic tangent and Gaussian functions. We use quasi-Newton...
In UWB communication system, to guarantee reliability and validity, receiver must know the characteristic of channel. Based on the difference and similarity between Rayleigh fading channel and UWB channel, we propose a modified channel estimation algorithm for MB-OFDM system considering complexity of cluster structure in UWB channel. Moreover, we make a parallel comparison of LS and MMSE algorithms...
