Abstract

[ES] En esta tesina se analiza la BEP, SEP, y la capacidad media en bit/simbolo de un sistema MB-OFDM-UWB utilizando modulación adaptativa M-PSK para canales dispersivos en tiempo con perfil de retardo de potencia exponencial y estadística Nakagami-m para modelar el desvanecimiento rápido del canal.

[EN] The standard of physical layer for ultra-wideband (UWB) systems with signaling Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM-UWB) certified on March 2007 by the ISO/IEC, specifies the UWB bandwidth division in 14 sub bands each of 528 MHz and fixed digital modulation QPSK for each of the 100 data subcarriers. In this thesis the performance capacity of the system MB-OFDM-UWB is analyzed using adaptive digital modulation M-PSK for a time dispersive channel with power delay profile (PDP) exponential and statistical Nakagami-m for to model the fast fading of the channel. The performance of the parameters to obtain: - The average bit and symbol error rate probability. - Average capacity in bits per symbol in function of the average SNR of the channel - The gain in diversity with M-PSK for a bit error probability threshold of 10-3 in function of the m parameter of the channel Nakagami-m
