IQ Imbalance,l intermediate frequency (IF) filters and image rejection filters . Instead, the image rejection is provided by the signal processing in the in-phase (I) and quadrature (Q) arm. Therefore, this architecture opens the door to monolithic integration of the analogue front-end and, thus, low-cost implementations.

Introduction,ch took place at the end of the 19th century and is attributed to Hertz. The technology was, shortly thereafter, commercialised by, amongst others, Marconi in one of the first wireless communication systems, i.e., wireless telegraphy. In the first half of the 20th century the technology was develope

Multiple-antenna OFDM systems,wireless systems provides the possibility to exploit the degrees of freedom provided by the spatial multiple-input multiple-output (MIMO) wireless channel. These systems are generally named after the channel used for the transmission, i.e., MIMO systems. To overcome the frequency selectivity and tim

Phase Noise,ising basis for next generation high data rate systems. The comparison between simulation and measurement results in Section 3.6.3, however, shows that a fair difference occurs between the theoretical and practical system performance. The discussion of the results highlights that imperfections in th

Nonlinearities,or the propagation channel, as discussed in Section 2.2, several elements in the transmitter (TX) and receiver (RX) analogue front-end can exhibit a nonlinear transfer. The major sources of nonlinearity are generally the analogue-to-digital (A/D) and digitalto- analogue (D/A) converters, mixers and

A generalised error model, chapter a first step is made towards the modelling of the composite severeness and impact of different RF impairments. Such a generalised impairment model has the major advantage that not all effects have to be investigated separately, but that the combined impact of all impairments can be captured
