Pseudo channel reciprocity in FDD satellite channels
Rei Richter, Itsik Bergel, Yair Noam +1
Channel reciprocity can significantly reduce the overhead of obtaining channel-state information at the transmitter (CSIT). However, true reciprocity only exists in time division d…
Asymptotic Performance of TDOA Estimation using Satellites
Hodaya Halevi, Itsik Bergel, Yair Noam
We present novel lower bounds on the localization error using a network of satellites randomly deployed on a sphere around Earth. Our new analysis approach characterizes the locali…
C-RAN Zero-Forcing with Imperfect CSI: Analysis and Precode\&Quantize Feedback
Niv Arad, Yair Noam
Downlink joint transmission by a cluster of remote radio heads (RRHs) is an essential technique for enhancing throughput in future cellular networks. This method requires global ch…
Lower Bound on the Localization Error in Infinite Networks with Random Sensor Locations
Itsik Bergel, Yair Noam
We present novel lower bounds on the mean square error (MSE) of the location estimation of an emitting source via a network where the sensors are deployed randomly. The sensor loca…
The One-Bit Null Space Learning Algorithm and its Convergence
Yair Noam, Andrea J. Goldsmith
This paper proposes a new algorithm for MIMO cognitive radio Secondary Users (SU) to learn the null space of the interference channel to the Primary User (PU) without burdening the…
Blind Null-space Tracking for MIMO Underlay Cognitive Radio Networks
Alexandros Manolakos, Yair Noam, Andrea J. Goldsmith
Blind Null Space Learning (BNSL) has recently been proposed for fast and accurate learning of the null-space associated with the channel matrix between a secondary transmitter and…
Spatial MAC in MIMO Communications and its Application to Underlay Cognitive Radio
Yair Noam, Andrea Goldsmith
We propose a learning technique for MIMO secondary users (SU) to spatially coexist with Primary Users (PU). By learning the null space of the interference channel to the PU, the SU…
Competitive Spectrum Management with Incomplete Information
Yair Noam, Amir Leshem, Hagit Messer
This paper studies an interference interaction (game) between selfish and independent wireless communication systems in the same frequency band. Each system (player) has incomplete…
