In this sequel to [1], the joint Tx/Rx I/Q imbalance model of mobile SC-FDE transceivers is extended to include the effect of residual carrier frequency offset. Furthermore, the equivalent channel model for multiple-antenna spatially-multiplexed SC-FDE transceivers in the presence of I/Q imbalance and mobility is derived and an effective digital baseband compensation scheme is proposed, and its performance...
Direct-conversion multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) transceivers enjoy high data rates and reliability at practical implementation complexity. However, analog front-end impairments such as I/Q imbalance and high mobility requirements of next-generation broadband wireless standards result in performance-limiting inter-carrier interference (ICI). In...
Direct-conversion orthogonal frequency division multiplexing (OFDM) systems suffer from transmit and receive analog processing impairments such as in-phase/ quadrature (I/Q) imbalance causing intercarrier interference (ICI) between the sub-carriers. Another source of performance-limiting ICI, but with a different nature, in OFDM systems is Doppler spread due to mobility. Unlike previous work which...
In-phase and quadrature-phase (I/Q) imbalance is a major performance-limiting impairment for direct- conversion orthogonal frequency division multiplexing (OFDM) transceivers. I/Q imbalance degrades the signal-to-noise-ratio in an OFDM system by causing inter-channel-interference (ICI) between image subcarriers. Doppler spread due to mobility also causes ICI but mainly between adjacent subcarriers...
