An Improved Peak-to-Average Power Ratio Estimation Scheme for OFDM Systems
—To approximate the exact peaks of continuous-time orthogonal frequency division multiplexing (OFDM) signals, four times oversampling is usually employed for discrete-time OFDM s...

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...

Iterative Correction of Clipped and Filtered Spatially Multiplexed OFDM Signals
— Peak-to-Average Power Ratio (PAPR) reduction in multicarrier systems with multiple transmit and receive antennas is considered. One attractive method for reducing the PAPR is t...
