Estima e Igualacion Ciega de Canales MIMO con y sin Redudancia Espacial (title in Spanish) (2007)
Abstract / truncated to 115 words
The majority of communication systems need the previous knowledge of the channel, which is usually estimated by means of a training sequence. However, the transmission of pilot symbols provokes a reduction in bandwidth efficiency, which precludes the system from reaching the limits predicted by the Information Theory. This problem has motivated the development of a large number of blind channel estimation and equalization techniques, which are able to obtain the channel or the source without the need of transmitting a training signal. Usually, these techniques are based on the previous knowledge of certain properties of the signal, such as its belonging to a finite alphabet, or its higher-order statistics. However, in the case of multiple-input ... toggle 3 keywordsblind channel estimation – MIMO – STBC
