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.…
A Low-Complexity Improved Successive Cancellation Decoder for Polar Codes
Orion Afisiadis, Alexios Balatsoukas-Stimming, Andreas Burg
Under successive cancellation (SC) decoding, polar codes are inferior to other codes of similar blocklength in terms of frame error rate. While more sophisticated decoding algorith…
Baseband and RF Hardware Impairments in Full-Duplex Wireless Systems: Experimental Characterisation and Suppression
Alexios Balatsoukas-Stimming, Andrew Charles Mallory Austin, Pavle Belanovic +1
Hardware imperfections can significantly reduce the performance of full-duplex wireless systems by introducing non-idealities and random effects that make it challenging to fully s…
Density Evolution for Min-Sum Decoding of LDPC Codes Under Unreliable Message Storage
Alexios Balatsoukas-Stimming, Andreas Burg
We analyze the performance of quantized min-sum decoding of low-density parity-check codes under unreliable message storage. To this end, we introduce a simple bit-level error mode…
