Correcting systematic mismatches in computed log-likelihood ratios
This work proposes post-processing of output LLRs to correct part of the mismatches, a function of the statistics of the input LLRs, which measures the reliability (and uncertainty) of a binary random variable being a zero versus being a one.
Enhanced C-V2X Mode-4 Subchannel Selection
A nonlinear power averaging phase, where the most up-to-date measurements are assigned higher priority via exponential weighting is proposed, and it is shown through simulations that the overall system performance can be leveraged in both urban and freeway scenarios.
Enumerative Sphere Shaping for Wireless Communications With Short Packets
Following Wachsmann et al., it is shown that for a given constellation and target rate, there is an optimum balance between the FEC code rate and the entropy of the Maxwell-Boltzmann distribution that minimizes the gap-to-capacity.
High rate reconciliation
A new reconciliation algorithm is discussed that can be used in general settings, and uses soft decision techniques, and high fates are already obtained for small block lengths.
IP-recovery in the DVB-H Link layer for TV on mobile
Using the derived locator information, experimental research has shown that after FEC, a considerable number of correct IP datagrams can still be recovered from an incorrect MPE-FEC frame, which results in up to 50% data recovery for medium-sizeddatagrams.
Partial Enumerative Sphere Shaping
Simulations over the AWGN channel exhibit that shaping 2 amplitude bits of 16-ASK have almost the same performance as shaping 3 bits, which is 1.3 dB more power- efficient than uniform signaling at a rate of 3 bit/symbol.
Graph-based resource allocation with conflict avoidance for V2V broadcast communications
This research has envisaged a solution based on a bipartite graph, where vehicles and spectrum resources are represented by vertices whereas the edges represent the achievable rate in each resource based on the signal-to-interference-plus-noise ratio (SINR) that vehicles perceive.
Parallel and successive resource allocation for V2V communications in overlapping clusters
This research considers overlapping clusters only, which could be formed at intersections or merging highways and shows through simulations that B GM-SA can attain near-optimal performance whereas BGM-PA is subpar but less complex.
Subchannel allocation for vehicle-to-vehicle broadcast communications in mode-3
Four types of conditions that are of forceful character for attaining QoS-aware conflict-free allocations have been identified and a surrogate relaxation of the problem is proposed that does not affect optimality provided that certain requisites are satisfied.
Quantum key agreement
We consider quantum key agreement between two users Alice and Bob in which an eavesdropper Eve intercepts and resends photons. We show how Alice and Bob attain a probabilistic upper bound on Eve's
