This article is a review of several classical and modern wireless receiver architectures used
in wideband wireless communication systems. The emphasis is on configurations suitable …

Wireless systems often make use of the quadrature relationship between pairs of signals to
effectively cancel out-of-band and interfering in-band signal components. The …

This paper addresses the estimation and compensation of I/Q imbalance, one of the most
prominent impairments found in wideband zero-intermediate frequency transceivers (TRxs) …

Changes in ambient temperature or chip temperature result in variations in the in-phase and
quadrature (I/Q) gain and phase imbalance. As a consequence, the overall system …

Under strong line-of-sight (LOS) conditions, in a conventional spatial modulation scheme,
the signal domain exhibits better error performance than the spatial domain, thus rendering …

Asymmetric modulation techniques like Quadrature Amplitude Modulation system is one of
the key techniques in building a broadband mobile communication network because of …

Abstract The Complex Block Least Mean Square (LMS) technique is widely used in adaptive
filtering applications because of its simplicity and efficiency from a theoretical and …

This paper considers the use of unequal error protection and median filtering for
transmission of images over poor wireless channels usually encountered over cellular …

Bit dependency of image compression algorithms introduce error extension effects in
transmission of compressed images and considerably reduce the received image quality …

Unequal Error protection (UEP) of wavelet coded video is investigated using Hierarchical
Quadrature Amplitude Modulation (HQAM). Based on the unequal sensitivity of coded bit …
