In this paper, a ZigBee-based sensor network is realized and evaluations are carried out in order to clarify the fundamental performance of this sensor network. Life recording and management system is introduced as an example of ZigBee-based sensor networks, and the system is introduced into mobile WiMAX network in Azumino city in order to solve some medical problems in local cities. The following...
Multi-carrier code division multiple access (MCCDMA) is one of promising broadband wireless access techniques. Frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can take advantage of the channel frequency-selectivity and improve the average bit error rate (BER) performance of single-code MC-CDMA due to frequency-diversity gain. However, as the code multiplexing...
c-Axis-oriented hexagonal Fe 3 N films were epitaxially grown on Si(111) substrates by molecular beam epitaxy using AlN/3C–SiC intermediate layers. Fe 3 N epitaxial film grown on AlN/3C–SiC/Si(111) has a smooth surface and atomically flat two-dimensional terraces. It was found that the magnetic moments of Fe 3 N epitaxial film faced parallel to the film plane, and that the...
