A Hybrid Scheme for TX I/Q Imbalance Self-Calibration in a Direct-Conversion Transceiver Open
A generic transmitter (TX) I/Q imbalance self-calibration method, which was designed based on a hybrid analog and digital structure, is proposed in this paper. The whole calibration scheme was implemented using low-complexity digital–analo…

The Evolving Role of Class in Choice of Fashion in Postmodern Society Open
Class plays a diminishing role in the criteria by which people choose fashion in today’s society. This means that in most cases, people no longer choose fashion according to their class status, but according to their personal preferences. …

A Frequency-Domain I/Q Imbalance Calibration Algorithm for Wideband Direct Conversion Receivers Using Low-Cost Compensator Open
The amplitude and phase imbalances of the in-phase (I) and quadrature (Q) branches inherent in the direct conversion receiver structure cause the generation of image frequency interference signals. In this paper, a frequency-domain I/Q imb…

A Blind Calibration Model for I/Q Imbalances of Wideband Zero-IF Receivers Open
Frequency-dependent I/Q imbalance and frequency-independent I/Q imbalance are the major impairments in wideband zero-IF receivers, and they both cannot be ignored. In this paper, a blind calibration model is designed for compensating these…
