This paper presents a VLSI architecture specifically designed as a video/communication controller to support emerging applications in the area of video/data communications. The controller is a parallel architecture consisting of three (3) processing modules, a shared memory with four (4) banks and two (2) input/output modules and operating at the transfer speed of 622 Mbits/sec. The processing modules and memory banks communicate through a low cost interconnection scheme able though to perform at system's required data transfer rate. The entire system constitutes a component which can accommodate a switching system as an intelligent buffer with real time processing and multiplexing capabilities. The component performs operations on fixed and/or variable length packets of data on a stream basis. The architecture embeds both the processing and the memory modules, thus producing a system on a chip solution. 相似文献

There is a continuous pursuit by mobile operators (MOs) to improve indoor coverage in order not only to improve voice quality but also to enable higher data rates in home/office environments. Indoor coverage improvement, in conjunction with inexpensive (voice) offerings, will enable MOs to compete with and take away voice-call-related revenues from fixed network PTTs and/or VoIP operators. Femtocells constitute a promising solution to address all of the above. In this article we present our experience from our extensive study and trials of early (pre-standard) femtocell solutions that were available in the 2007-2008 timeframe. 相似文献

Third-generation mobile systems are emerging. These systems will support a unified user access to a variety of services, including the existing mobile and fixed network (PSTN, N-ISDN) services, the enhanced multimedia and multiparty services envisaged for broadband networks, and personal communication services as well. The role of signaling is predominant in building a flexible, efficient, and evolving system. The aim of this paper is to provide a framework for developing a signaling protocol architecture for future mobile networks. The study especially focuses on the universal mobile telecommunication system (UMTS). Within this framework various design and operational requirements imposed on UMTS can be satisfied. A method to deal with the functional complexity of UMTS is provided. Mobile networks are viewed as integral parts of the broadband infrastructure and are built upon the IN principles. 相似文献
