Mobile WiMAX aims to provide multimedia multicast/broadcast service (MBS) as well as elastic data service. However, supporting delay sensitive applications like video/audio streaming is still challenging, which requires both efficient handling of link bandwidth and reducing handover delays. To reduce the handover delay in MBS, the IEEE 802.16e standard defines an MBS zone, which is a group of base...
Recently, the high-rate data transmission has been one of key issues in wireless mobile communications. MIMO (multiple-input multiple-output) is an emerging technology offering high spectral efficiency with the improved link reliability and interference suppression. In this paper, we introduce the basic concept of space-time code and extend to LST (layered space-time) architecture, especially V-BLAST...
