In 4G systems, multimedia data will be streamed over various wireless networks to a multitude of portable devices. Hence, a large number of users will soon be able to access multimedia data at anytime, and from anywhere. However there exists a gap between the user requirements and the available systems. In this paper we present across layer technique called Interactive Video Switching (IVS) that is...
The WiMAX standard has emerged to harmonise the wide variety of broadband wireless access (BWA) technologies. The recent mobile WiMAX standard (802.16e) supports broadband applications to mobile terminals and laptops in urban environments. Mobile WiMAX supports a full range of multiple-input multiple-output (MIMO) techniques including space time block coding (STBC), spatial multiplexing (SM) and eigen-beamforming...
The performance of the uplink (UL) and downlink (DL) of IEEE 802.16e-2005 or Worldwide Inter-Operability Microwave Access (WiMAX) standard is studied via extensive computer simulations in this paper. The channel estimation is introduced and its impact on the system performance is evaluated under different channel conditions. The main contribution is to address the impact of the hybrid automatic repeat...
The future mobile communication system will be distinguished by high integration of services, flexibility and higher throughput. Thus, the rapid growth in traffic volume and increase in new services has begun to change the configuration and structure of wireless networks. In the past, WiMAX has gained lot of interest for providing broadband communication. The present demand in the field of wireless...
