Ultra Wide Band (UWB) technology is nowadays emerging as a strong candidate for indoor wireless applications, thanks to its low power consumption and high data rates. On the other hand, the use of multiple antennas in transmission and/or reception aims to achieve spatial diversity. It offers significant increases in data throughput without additional(More)
In this work we consider the optimization of the cell number to configure the different clusters in a coordinated multipoint transmission downlink environment where block diagonalization is employed to remove interference among users inside each cluster. Two possible schemes for the power allocation to each user's transmission are compared, namely uniform(More)
In this paper, a novel scheme for reducing the envelope fluctuations in OFDM (Orthogonal Frequency division Multiplexing) based on ANFIS (Adaptive Neural Fuzzy Inference Systems) is evaluated when some data can not be modified such as pilot sub-carriers. The loss on the envelope fluctuation reduction is shown to be smaller than 0.3 dB when the proportion of(More)
