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...
Abstract--Physical transceiver implementations for multipleinput multiple-output (MIMO) wireless communication systems suffer from transmit-RF (Tx-RF) impairments. In this paper, w...
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 we propose a generally applicable frequency domain equalization and radio frequency (RF) impairment compensation technique for orthogonal frequency division multiple...
— OFDM multi-carrier modulation is expected to be the enabling technology for 4G wireless systems. One of the features that make OFDM the primary choice for 4G is its MIMO compat...
