Energy-Efficient Hardware-Accelerated Synchronization for Shared-L1-Memory Multiprocessor Clusters
Florian Glaser, Giuseppe Tagliavini, Davide Rossi +3
The steeply growing performance demands for highly power- and energy-constrained processing systems such as end-nodes of the internet-of-things (IoT) have led to parallel near-thre…
EC-GSM-IoT Network Synchronization with Support for Large Frequency Offsets
Stefan Lippuner, Benjamin Weber, Mauro Salomon +2
EDGE-based EC-GSM-IoT is a promising candidate for the billion-device cellular IoT (cIoT), providing similar coverage and battery life as NB-IoT. The goal of 20 dB coverage extensi…
An 826 MOPS, 210 uW/MHz Unum ALU in 65 nm
Florian Glaser, Stefan Mach, Abbas Rahimi +3
To overcome the limitations of conventional floating-point number formats, an interval arithmetic and variable-width storage format called universal number (unum) has been recently…
Optimal Channel Shortener Design for Reduced-State Soft-Output Viterbi Equalizer in Single-Carrier Systems
Sha Hu, Harald Kröll, Qiuting Huang +1
We consider optimal channel shortener design for reduced-state soft-output Viterbi equalizer (RS-SOVE) in single-carrier (SC) systems. To use RS-SOVE, three receiver filters need t…
Maximum-Likelihood Detection for Energy-Efficient Timing Acquisition in NB-IoT
Harald Kroll, Matthias Korb, Benjamin Weber +2
Initial timing acquisition in narrow-band IoT (NB-IoT) devices is done by detecting a periodically transmitted known sequence. The detection has to be done at lowest possible laten…
A Low-complexity Channel Shortening Receiver with Diversity Support for Evolved 2G Device
Sha Hu, Harald Kroll, Qiuting Huang +1
The second generation (2G) cellular networks are the current workhorse for machine-to-machine (M2M) communications. Diversity in 2G devices can be present both in form of multiple…
A Signal Processor for Gaussian Message Passing
Harald Kröll, Stefan Zwicky, Reto Odermatt +3
In this paper, we present a novel signal processing unit built upon the theory of factor graphs, which is able to address a wide range of signal processing algorithms. More specifi…
