A. Rezola, J. F. Sevillano, M. Leyh, M. Lorenzo, R. Berenguer, A. Vargas, I. Vélez. Non-frequency-selective IQ Imbalance in Zero-IF Transceivers for Wide-Band mmW Links.The Tenth International Conference on Wireless and Mobile Communications (ICWMC 2014).June 22 - 26, 2014.Seville.

Abstract:

Millimeter wave (mmW) links are an attractive solution for backhaul of mobile networks. In order to cope with the requirements of future networks, these mmW links should achieve Gigabit data rates. These data rates can be achieved using wide-band and high order modulations in E-Band. Zero- IF architectures are good candidates for integrated transceivers. However, the design of integrated transceivers at these frequencies is a challenging issue. An important source of degradation is I/Q imbalance, which can significantly reduce the performance of a communication system with zero-IF transceivers if it is not appropriately compensated. In this paper the impact of the IQ imbalance impairment on the transmitted and received signal is analyzed and suitable digital signal processing techniques are evaluated for IQ imbalance compensation at the receiver for a 64-QAM system using 2GHz bandwidth.
