Sliding Window Spectrum Sensing for Full-Duplex Cognitive Radios with Low Access-Latency
Orion Afisiadis, Andrew C. M. Austin, Alexios Balatsoukas-Stimming +1
In a cognitive radio system the failure of secondary user (SU) transceivers to promptly vacate the channel can introduce significant access-latency for primary or high-priority use…
Spatial Multiplexing of QPSK Signals with a Single Radio: Antenna Design and Over-the-Air Experiments
Mohsen Yousefbeiki, Andrew C. M. Austin, Juan R. Mosig +2
The paper describes the implementation and performance analysis of the first fully-operational beam-space MIMO antenna for the spatial multiplexing of two QPSK streams. The antenna…
Near-Field Perturbation Effect on Constellation Error in Beam-Space MIMO
Mohsen Yousefbeiki, Juan R. Mosig, Andreas P. Burg
Beam-space MIMO has recently been proposed as a promising solution to enable transmitting multiple data streams using a single RF chain and a single pattern-reconfigurable antenna.…
Hardware Decoders for Polar Codes: An Overview
Pascal Giard, Gabi Sarkis, Alexios Balatsoukas-Stimming +5
Polar codes are an exciting new class of error correcting codes that achieve the symmetric capacity of memoryless channels. Many decoding algorithms were developed and implemented,…
