Therefore, this architecture opens the door to monolithic integration of the analogue front-end and, thus, low-cost implementations.作者: Mendicant 時間: 2025-3-23 15:15 作者: misanthrope 時間: 2025-3-23 20:14 作者: addict 時間: 2025-3-23 23:52
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.

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.

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 作者: choroid 時間: 2025-3-25 01:22
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作者: 與野獸博斗者 時間: 2025-3-25 07:21
Discussion and conclusions, broadband wireless systems has been reported in many contributions over the last few years. A first reason is the high spectral efficiency, which is achieved by both techniques: OFDM places the subcarriers very close together and MIMO applies multiple spatial branches to transmit multiple parallel 作者: 高興去去 時間: 2025-3-25 08:34 作者: gratify 時間: 2025-3-25 13:52 作者: 負(fù)擔(dān) 時間: 2025-3-25 19:14

Design and implementation of a MIMO OFDM system,ynchronisation of the MIMO OFDM system is regarded in Sections 3.3 to 3.5. The algorithms are designed to exploit the transmission structures proposed in Section 3.2.

Phase Noise,evious studies, see e.g. [25, 26, 33, 89-95]. Since, in general, the disturbance of the amplitude of the oscillator output is marginal [96], most influence of the oscillator imperfection is noticeable in random deviation of the frequency of the oscillator output. These frequency deviations are often作者: 高爾夫 時間: 2025-3-27 02:21
Nonlinearities, parts of the RF front-end. Two conventional solutions to overcome this problem are either to use highly linear components for the front-end or to apply a large input power backoff (BO) when feeding the signals to the nonlinear components, as such ensuring that the signals experience the linear part作者: Fraudulent 時間: 2025-3-27 06:35
A generalised error model,ulting from all implementation deficiencies has to be known. Generally, though, it is assumed to be a zero-mean complex Gaussian process.
