Abstract— In this paper, we propose a distributed opportunistic access scheme for uplink OFDMA systems. The sub-carriers are grouped into several sub-channels. Users access these...
— In this paper, we compare two selective-repeat automatic-repeat-request (SR-ARQ) protocols for spatial multiplexing multiple-input multiple-output (MIMO) orthogonal frequency-d...
Poor sound pick up by remote microphones in multimedia applications, conference rooms and auditoria has traditionally hampered recording and communicating among spatially-separate...

- Even though state-of-the-art FPGAs present new opportunities in exploring low-cost high-performance architectures for floating-point scientific applications, they also pose serio...
— One of the primary impediments to building ensembles with many modular robots is the complexity and number of mechanical mechanisms used to construct the individual modules. As...
