Abstract

Wideband mmW communication systems suffer from a series of imperfections that can greatly jeopardize the signal quality. One of the most detrimental effects is the frequency-selective I/Q imbalance, which is present in most wideband mmW transceivers. This chapter analyzes the frequency-selective I/Q imbalance in detail, explaining its mathematical fundamentals and outlining methods to detect and compensate for it.
