Abstract— Two-way relaying, which enables bidirectional simultaneous data transmission between two nodes, is an efficient means to reduce the spectral efficiency loss observed ...
Abstract—The high peak-to-average-power ratio (PAR) of Orthogonal Frequency Division Multiplexing (OFDM) transmission systems significantly reduces the power efficiency or perf...
—WiMAX mesh mode, recently standardized, enables direct communications between subscriber stations without referring to the base station (BS). It can be a great solution for prov...
—Key factors of indoor NLoS radio channels are examined, namely the number of channel taps, the mean delay, the RMS delay spread and the channel gain. We analyze wideband (2-11 G...
— Future mobile communications systems demand for higher data rates and service quality compared to state-of-the-art systems. One way to achieve this ambitious goal is to use rel...
—One of the major problems of deploying RSVP in the mobile environment is called the advance resource reservation problem. If an RSVP reservation path is reserved in advance in t...
Abstract—We present two interference alignment techniques such that an opportunistic point-to-point multiple input multiple output (MIMO) link can reuse, without generating any a...
Abstract—In multi-user multiple-input multiple-output (MUMIMO) systems, spatial multiplexing can be employed to increase the throughput without the need for multiple antennas and...
