Sparse Non-Negative Recovery from Biased Subgaussian Measurements using NNLS
Yonatan Shadmi, Peter Jung, Giuseppe Caire
We investigate non-negative least squares (NNLS) for the recovery of sparse non-negative vectors from noisy linear and biased measurements. We build upon recent results from [1] sh…

Truncated Polynomial Expansion Downlink Precoders and Uplink Detectors for Massive MIMO
Andreas Benzin, Giuseppe Caire, Yonatan Shadmi +1
In TDD reciprocity-based massive MIMO it is essential to be able to compute the downlink precoding matrix over all OFDM resource blocks within a small fraction of the uplink-downli…
