Mitigating SAR-ADC Non-Idealities in Massive MU-MIMO Systems via Affine Models
Jérémy Guichemerre, Christoph Studer
Low-resolution data converters can significantly reduce the power consumption and silicon area of all-digital massive multi-user (MU) multiple-input multiple-output (MIMO) basestat…
The Influence of Gain and Phase Mismatches on Beam Patterns in Phased Arrays
Jérémy Guichemerre, Christoph Studer
Practical implementations of phased arrays suffer from per-antenna gain, phase, and delay mismatches, which can significantly worsen the maximum sidelobe level (SLL) of beampattern…
Spectral Impact of Mismatches in Interleaved ADCs
Jérémy Guichemerre, Robert Reutemann, Thomas Burger +1
Interleaved ADCs are critical for applications requiring multi-gigasample per second (GS/s) rates, but their performance is often limited by offset, gain, and timing skew mismatche…
A 14ns-Latency 9Gb/s 0.44mm 62pJ/b Short-Blocklength LDPC Decoder ASIC in 22FDX
Darja Nonaca, Jérémy Guichemerre, Reinhard Wiesmayr +2
Ultra-reliable low latency communication (URLLC) is a key part of 5G wireless systems. Achieving low latency necessitates codes with short blocklengths for which polar codes with s…
The Impact of SAR-ADC Mismatch on Quantized Massive MU-MIMO Systems
Jérémy Guichemerre, Christoph Studer
Low-resolution analog-to-digital converters (ADCs) in massive multi-user (MU) multiple-input multiple-output (MIMO) wireless systems can significantly reduce the power, cost, and i…
