One limiting issue in implementing high-speed wireless systems is the impairment associated with analog processing due to component imperfections. In uplink transmission of multiu...
— In this paper, we analyze the effects of IQ (In-phase/ Quadrature-phase) imbalances at both transmitter and receiver of OFDM (Orthogonal Frequency Division Multiplexing) system...
— I/Q imbalance has been identified as one of the most serious concerns in the practical implementation of the direct conversion receiver architecture. Facing the performance-de...
Abstract— This contribution analytically studies the influence of IQ mismatch on the performance of multiple-antenna orthogonal frequency division multiplexing (OFDM) systems ba...
