Results on penetration measurements through different materials at the terahertz band (0.1 – 10 THz) are reported. These materials include common materials found at any home or office, i.e., plastic, glass, paper, and hardboard. The measurements were conducted with terahertz time domain spectroscopy (THz-TDS) method and with the TeraView TeraPulse measurement device. The results show that the THz...
The self-interference (SI) channel in full duplex transceivers is investigated. The SI channel is measured using ultra wide-band antennas. Narrow-band measurement technique is used for the channel measurements so that spatial resolution of 4.3 cm is achieved. Measurements are done in a variety of locations including an anechoic chamber with different antenna orientation. Antennas are mounted on an...
We consider the sum power minimization problem with user specific rate constraint in the context of uplink LTE-A type system with carrier aggregation (CA), more precisely, inter-band CA. The increased bandwidth in LTE-A system allows orthogonal allocation of subcarriers among users. If time sharing or non-linear receivers are assumed, the problem becomes convex and can be optimally solved by standard...
A multirate transmission scheme to mitigate intersymbol interference (ISI) is proposed in this paper. The proposed method first decomposes the channel into two half-rate subchannels by employing successive interference cancellation (SIC). Then the channel is further decomposed into 2M parallel channels by applying the method recursively. We demonstrate that these sub-channels tend to become memoryless...
