Fundamental Limits of Dynamic Tracking and Communication: A Stationary Policy Formulation
Mohammadreza Bakhshizadeh Mohajer, Luca Barletta, Alex Dytso +1
We study a dynamic integrated sensing-and-communication problem in which a multi-antenna transmitter communicates with a receiver while simultaneously tracking a moving target gove…
A Two-Term Ziv-Zakai Bound for Multitarget DoA Estimation in MIMO Radar
Mohammadreza Bakhshizadeh Mohajer, Daniela Tuninetti, Luca Barletta
Multitarget direction of arrival (DoA) estimation is challenging when fluctuating targets are closely spaced: local Cramér--Rao bounds (CRBs) miss global errors, while direct vecto…
A Rate-Distortion Bound for Integrated Sensing and Communication
Mohammadreza Bakhshizadeh Mohajer, Alex Dytso, Daniela Tuninetti +1
We develop a general rate--distortion bound (RDB) for the fundamental sensing--communication tradeoff in integrated sensing and communication (ISAC) systems. The RDB lower-bounds t…
A Poincaré Lower Bound Approach for Performance Trade-offs in MIMO ISAC Systems with Blockage
Mohammadreza Bakhshizadeh Mohajer, Luca Barletta, Daniela Tuninetti +3
Characterizing the performance trade-offs between sensing and communication subsystems is essential for enabling integrated sensing and communication systems. Various metrics exist…
MMSE Channel Estimation in Fading MIMO Gaussian Channels With Blockage: A Novel Lower Bound via Poincaré Inequality
Mohammadreza Bakhshizadeh Mohajer, Luca Barletta, Daniela Tuninetti +3
Integrated sensing and communication is regarded as a key enabler for next-generation wireless networks. To optimize the transmitted waveform for both sensing and communication, va…
On the Achievable Rate of MIMO Narrowband PLC with Spatio-Temporal Correlated Noise
Mohammadreza Bakhshizadeh Mohajer, Sadaf Moaveninejad, Atul Kumar +4
Narrowband power line communication (NB-PLC) systems are an attractive solution for supporting current and future smart grids. A technology proposed to enhance data rate in NB-PLC…
