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...
In this paper, a practical approach for detecting packet-based orthogonal frequency division multiplexing (OFDM) signals in the presence of phase noise is presented. An OFDM packe...
—In this paper, we propose a novel channel estimation scheme for the broadcast phase of the newly invented twoway relaying technique. Instead of using pilot sequences, we exploit...

In this paper, the issue of channel estimation with multiple In-Cell co-channel Users (ICUs) in the presence of Out of Cell Interferers (OCIs) is addressed. A Single Carrier Frequ...
