We investigate a home entertainment and computing network proposal, which takes advantage of UWB impulse radio technology. Time hopping combined with pulse position modulation represents the original proposal for UWB communication systems. Recently, other schemes have been considered in order to obtain better performance in particular scenarios. OFDM-based UWB system uses OFDM modulation with a frequency hopped pulse train in order to achieve full multipath diversity in multipath fading channels. Direct sequence code division multiple access is well known as a powerful multiple-access technique in the presence of strong narrowband interference. We investigate modulation schemes (DSC, OFDM) and design approach (LDPC) for improving the performance of home entertainment network.
