Analog representation and digital implementation of OFDM systems
Many existing results on the analysis of OFDM systems are based on an analog representation. The actual implementation of OFDM transmitters typically consists of a discrete DFT ma...

Efficient Algorithms for PAPR Reduction in OFDM Transmitters Implemented using Fixed-Point DSPs
OFDM has a very high peak-to-average power ratio. This imposes stringent dynamic range requirements on the analog front-ends of the transmitter and receiver and, if a fixedpoint pr...

STBC MIMO OFDM Systems with Implementation Impairments
Multi-input multi-output (MIMO) systems are often realized with low cost front-end architectures, e.g. the so called direct conversion architectures. However, such systems are ver...

Verification-Oriented Behavioral Modeling of Non-Linear Analog
In this work, an approach to the `verification-oriented' modeling of the analog parts' behavior of mixed-signal circuits is presented. Starting from a continuous-time, c...

On the Joint Compensation of IQ Imbalances and Phase Noise in MIMO-OFDM Systems
Abstract— OFDM systems are susceptible to receiver impairments such as IQ imbalance and phase noise. These impairments can severely degrade the achievable effective signalto-nois...
