Energy-Efficient Power Control in Single-User M-MIMO-OFDM System with PA Nonlinearity
Siddarth Marwaha, Pawel Kryszkiewicz, Eduard A. Jorswieck
Although multiple works have proposed energy-efficient resource allocation schemes for Massive Multiple-Input Multiple-Output (M-MIMO) system, most approaches overlook the potentia…
Optimal Distortion-Aware Multi-User Power Allocation for Massive MIMO Networks
Siddarth Marwaha, Pawel Kryszkiewicz, Eduard Jorswieck
Real-world wireless transmitter front-ends exhibit certain nonlinear behavior, e.g., signal clipping by a Power Amplifier (PA). Although many resource allocation solutions do not c…
Nonlinear symbols combining for Power Amplifier-distorted OFDM signal reception
Pawel Kryszkiewicz, Hanna Bogucka
Nonlinear distortion of a multicarrier signal by a transmitter Power Amplifier (PA) can be a serious problem when designing new highly energy-efficient wireless systems. Although t…
An Open-RAN Testbed for Detecting and Mitigating Radio-Access Anomalies
Hanna Bogucka, Marcin Hoffmann, Paweł Kryszkiewicz +1
This paper presents the Open Radio Access Net-work (O-RAN) testbed for secure radio access. We discuss radio-originating attack detection and mitigation methods based on anomaly de…
Power Amplifier-Aware Transmit Power Optimization for OFDM and SC-FDMA Systems
Pawel Kryszkiewicz
The Single Carrier-Frequency Division Multiple Access (SC-FDMA) is a transmission technique used in the uplink of Long Term Evolution (LTE) and 5G systems, as it is characterized b…
