In this article, we show that the non-ideal Radio-Frequency (RF) front-ends have to be corrected in order to contribute in a Green radio development. In fact, the effects of typical RF imperfections, like nonlinearities, carrier frequency offsets, and IQ imbalances, can be compensated for, when digital correction algorithms are applied. Such algorithms(More)
We propose a new algorithm for the IQ imbalance estimation and equalization of an Orthogonal Frequency Division Multiplexing (OFDM) system in the presence of a Carrier Frequency Offset (CFO) and of a dense multipath environment. Our algorithm has a low complexity and needs a single pilot symbol. Through numerical simulation and in the context of quick(More)
