- MIMO OFDM Receivers for Systems With IQ Imbalances
- Orthogonal frequency division multiplexing OFDM is a widely recognized modulation scheme for high data rate communications. However, the implementation of OFDM-based systems suffers from in-phase and quadrature-phase IQ imbalances in the front-end analog processing. Such imbalances are caused by the analog processing of the received radio frequency RF signal, and...
