Sharp Analysis of RLS-based Digital Precoder with Limited PAPR in Massive MIMO

no code implementations24 May 2022 Xiuxiu Ma, Abla Kammoun, Ayed M. Alrashdi, Tarig Ballal, Tareq Y. Al-Naffouri, Mohamed-Slim Alouini

We show that for this class of precoders, there is an optimal transmit per-antenna power that maximizes the system performance in terms of SINAD and bit error probability.

Precise Performance Analysis of the Box-Elastic Net under Matrix Uncertainties

no code implementations11 Jan 2019 Ayed M. Alrashdi, Ismail Ben Atitallah, Tareq Y. Al-Naffouri

In this letter, we consider the problem of recovering an unknown sparse signal from noisy linear measurements, using an enhanced version of the popular Elastic-Net (EN) method.

Precise Performance Analysis of the LASSO under Matrix Uncertainties

no code implementations13 Aug 2018 Ayed M. Alrashdi, Ismail Ben Atitallah, Tareq Y. Al-Naffouri, Mohamed-Slim Alouini

In this paper, we consider the problem of recovering an unknown sparse signal $\xv_0 \in \mathbb{R}^n$ from noisy linear measurements $\yv = \Hm \xv_0+ \zv \in \mathbb{R}^m$.
