Carl Ingemarsson

I took my master at Linköping University in 2009 and then was enrolled as a PhD student at the Electronics Systems division at Dept. of Electrical Engineering (ISY). Since summer 2014 I am instead enrolled at division of Computer Engineering at dept. of Electrical Engineering at Linköping University.


My main research focus lies in the implementation of signal processing algorithms and arithmetics in hardware. I have studied the hardware implementation of matrix inversion, and is currently working more with this in connection with the possible application of matrix inversion in MIMO decoding. I have also spent effort studying the mapping of hardware architectures towards FPGA technology.


During my time as PhD student have been involved as either lab assistant, student project supervisor, or tutorial session teacher in many different undergraduate course, for instance:

TSTE12 - Konstruktion av digitala system
TSIU05 - Digitalteknik
TSEA51 - Digitalteknik
TSEA57/82 - Datorteknik
TSTE20 - Elektronik
TSTE87 - Application specific Integrated Circuits for Digital Signal Processing
TMEL08 - Elektrotekniska system
TMMI04 - Elektroteknik
