The expressions of the transverse electric (TE) and transverse magnetic (TM) modes of the isosceles right triangular waveguides with unusual boundary conditions are discussed in this paper. Based on the initial solution formed using a finite sum of rectangular harmonics, boundary conditions are discussed, and TE and TM mode expressions are presented in this paper for the isosceles right triangular...
Most research works of interference alignment (IA) focus on the symmetric networks. When the difference of path loss is considered in asymmetric networks, topology management (TM) needs to be carefully designed for IA-based interference networks, through separating the network into an IA subnetwork and some spatial multiplexing (SM) subnetworks. Nevertheless, the resource allocation problem has been...
Full-duplex radios are often envisioned to double wireless link capacity. Substantial work has focused on redesigning the radio hardware to achieve this theoretical gain. From a network-protocol perspective, however, it remains an open problem how to exploit full-duplex radio, and how much gain it can achieve in practical multi-cell wireless LANs. In this paper, we propose FuMAC, a channel access...
In a multi-user MIMO (MU-MIMO) network, an AP with M antennas can only serve up to M users out of a large user population. The M users' rates are inter-coupled and depend on their channel orthogonality. Substantial theoretical studies focused on selecting users to maximize capacity, but they require feedback of channel state information (CSI) from all users. The resulting overhead can easily overwhelm...
