In massive multi-user multiple-input-multiple-output (MU-MIMO) communication systems, high interconnect data rates are a major problem when the number of antennas at the base station increases. For some years, decentralized approaches have been propo

While centralized linear equalization algorithms can achieve a near optimal uplink detection performance for Massive MIMO systems at the base station, the required interconnect and off-chip input/output data rates surpass the bandwidth of existing in

Bivariate function approximation has proven its feasibility in terms of hardware-efficient arithmetic signal processing. However, its impact on high performance QR decomposition (QRD) has only been roughly studied so far. In this paper, a novel hardw

While linear equalization schemes like zero forcing or minimum mean-square error achieve a near optimal uplink signal estimation performance in large-scale multi-user multiple-input multiple-output systems, the corresponding algorithms lean on centra

In this paper, a block extended coordinate descent algorithm is introduced for MMSE based soft-output massive MIMO signal detection, which exploits the simple inversion of small sub-Gram matrices to allow a low-complexity implementation. We show that

In this paper a new approach for a fast and low-precision number format is explored. The SORN representation uses a fixed set of exact values and open intervals in between to represent real numbers on the digital layer. With SORN arithmetic operation

In this paper an adaptive hardware architecture for high-performance bivariate numerical function approximation is presented. Orthogonal Chebyshev-Polynomials are exploited that cover incremental accuracy refinements. Additionally, switching between

Massive MIMO systems have become more popular in wireless communications due to their improved spectral efficiency compared to existing small-scale MIMO systems. However, current estimation methodes take too long for larger numbers of antennas. In th

Inpainting-based compression and reconstruction methodology can be applied to systems with limited resources to enable continuously monitor neurological activity. In this work, an approach based on sparse representations and K-SVD is augmented to a v
