— The QR decomposition is an important, but often underestimated prerequisite for pseudo-or non-linear detection methods such as successive interference cancellation or sphere decoding for multiple-input multiple-output (MIMO) systems. The ability of concurrent iterative sorting during the QR decomposition introduces a moderate overall latency, but provides(More)
The development of state-of-the-art wireless communication transceivers in semiconductor technology is a challenging process due to complexity and stringent requirements of modern communication standards such as IEEE 802.11n. This tutorial paper describes a complete design, verification, and performance characterization methodology that is tailored to the(More)
The paper describes an algorithm and a corresponding VLSI architecture for the implementation of linear MMSE Idle Dtat Idle detection in packet-based MIMO-OFDM communication systems. The advantages of the presented receiver architecture are low latency, high-throughput, and efficient resource utilization, MIMO detectioni since the hardware required for the(More)
Introduced in 1999, differential power-analysis (DPA) attacks pose a serious threat for cryptographic devices. Several countermeasures have been proposed during the last years. However, none of them leads to implementations that are provably resistant against DPA. A promising class of DPA countermeasures is masking. In this article we discuss(More)
The performance of an FPGA-based MIMO-OFDM testbed is investigated through measurements. The setup includes two real-time terminals, supporting up to 4 spatial streams, and a wideband multipath channel emulator. The performance of the system, transmitting at data rates up to 216 Mbit/s over a 20 MHz channel in the 2.4 GHz ISM band, is benchmarked under(More)
