Main Objectives and Design Problems in future High Data Rate Mobile Communications Systems
نویسنده
چکیده
Mobility and Broadband Communications are becoming increasingly important. The potentials of present Mobile Communications Systems confine to dedicated services like voice communication with limited data communication capabilities or wireless LANs (WLAN). Due to the heterogeneous communication requirements, known from the Broadband-ISDN (BISDN) developement (continuous or bursty traffic characteristics, bandwidth, Quality of Service, QoS), the system has to be designed in particular under aspects of subscriber mobility and application bandwidth. This paper concerns to the design of Mobile Broadband Communications Systems in 60 GHz frequency band. Main design objectives are explained and technical problems discussed.

Design and Evaluation of a Method for Partitioning and Offloading Web-based Applications in Mobile Systems with Bandwidth Constraints
Computation offloading is known to be among the effective solutions of running heavy applications on smart mobile devices. However, irregular changes of a mobile data rate have direct impacts on code partitioning when offloading is in progress. It is believed that once a rate-adaptive partitioning performed, the replication of such substantial processes due to bandwidth fluctuation can be avoid...

The forthcoming mobile communication systems are expected to provide a wide variety of services, from high-quality voice to high-definition videos, through high-data-rate wireless channels anywhere in the world. The high data rate requires broad frequency bands, and sufficient broadband can be achieved in higher frequency bands such as microwave, Ka-band, and millimeter-wave. Broadband wireless...
متن کاملOptimization Capabilities of LMS and SMI Algorithm for Smart Antenna Systems (RESEARCH NOTE)
In the present paper convergence characteristics of Sample matrix Inversion (SMI) and Least Mean Square (LMS) adaptive beam-forming algorithms (ABFA) are compared for a Smart Antenna System (SAS) in a multipath environment. SAS are employed at base stations for radiating narrow beams at the desired mobile users. The ABFA are incorporated in the digital signal processors for adjusting the weight...
