Full-Duplex GFDM Radio Transceivers in the Presence of Phase Noise, CFO\n and IQ Imbalance
Bibliographic record
Abstract
This paper addresses the performance of a full-duplex (FD) generalized\nfrequency division multiplexing (GFDM) transceiver in the presence of radio\nfrequency (RF) impairments including phase noise, carrier frequency offset\n(CFO) and in-phase (I) and quadrature (Q) imbalance. We study analog and\ndigital self-interference (SI) cancellation and develop a complementary SI\nsuppression method. Closed-form solutions for the residual SI power and the\ndesired signal power and signal-to-interference ratio (SIR) are provided.\nSimulation results show that the RF impairments degrade SI cancellation and FD\nGFDM is more sensitive to them compares to FD orthogonal frequency division\nmultiplexing (OFDM). Hence, we propose an FD GFDM receiver filter for\nmaximizing the SIR. Significantly, it achieves 25 dB higher SIR than FD OFDM\ntransceiver.\n

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
