Space-time coded wireless transmission techniques with multiple transmit and receive
antennas can provide considerable increases in both the link quality as well as link capacity …

Analog and radio frequency (RF) front-end circuit impairments such as mismatches between
in-phase (I) and quadrature (Q) branches can severely degrade performance of wireless …

The gain/phase imbalances and DC-offsets in the in-phase and quadrature branches in
direct conversion transmitters (DCTs) are main sources of errors, especially at microwave …

The combination of orthogonal frequency division multiplexing (OFDM) and multiple-input
multiple-output (MIMO) techniques has been widely considered as the most promising …

This paper presents the simulation analysis of sensitivity of Singular Value Decomposition-
precoded MIMO on the direct conversion front-end impairments. Besides the major …

Direct conversion receivers are attractive for low cost systems as they avoid intermediate
frequency (IF) filters. However, the direct conversion from radio frequencies (RF) to complex …
