System interconnect analysis 4G high-speed bus architecture. - 4G, Broadband - The communications industry
1, Introduction to persuade Marconi from 1897 until the station would be completed. The wireless communication between the trial began, the wireless communication technology is developing rapidly. Communications industry, today's communication technology hot on third generation mobile communications. (3G) radio frequency with high efficiency using a fast and convenient high-speed wireless transmission with high-speed data and to use multimedia services. (The minimum transfer speed of up to 384k. 2M) Although 3G systems compared to conventional systems. 2G times the speed of transmission. But still can not meet future demand for multimedia communications. Communication in the future. Core services for customers to easily access Information and advice for the future of global communication is high-speed Internet service market have. (Broadband), immediately around the world (globalization). (Immediacy) and migration (mobility) in order to achieve this goal, we do not have limited access to high-speed Internet and high-speed integrated communications network. However, with the wireless Network speed and the integration of the core network as well. 3G features including the use of communications networks today are not mobile and the development of wireless communications. 4G Wireless Internet access has become essential support. Undeveloped unity of the international communications standards. 4G, the developed world. Hope in the future. 4G standards to to get jobs in Europe and the United States and Japan were investing heavily in long-term research and development in China. 2002 also launched a research and development. 4G general Synchronization between the countries.
The prediction uses 4G many of the new generation of advanced communications technologies such as OFDM, SDR, MIMO and smart antennas Space time - the highest price, up to code. 100 MB / s for future high-bandwidth requirements of real-time multimedia services for business needs. But with this latest technology, the widespread use of the new system. The complexity of the algorithm and the transmission system operator performance over previous versions of this priority. Increasing the number of processing control unit to provide high performance bandwidth and flexible interconnect architecture. 4G wireless communications system design challenges. Problem
2.4 G-platform architecture for the problem.
(1) The digital baseband processor of the increasing complexity of the algorithm
Communication systems. 4G phones are introduced in the wireless communications technology. MIMO is the distribution access by multiple stations. Other antennas for transmitting and receiving simultaneously, transmitter and receiver by the radio station. An input single output system (SISO) log (MIMO) channel can be viewed as a set of MIMO. parallel sub-channels to the capacity of all channels regardless of the channel capacity of quantum channels and in theory, a growing number of antennas. Significantly increase the capacity of the channel to the wireless network to improve on the data line, expand coverage and improve the quality of the proposals, which could well happen. But among multiple antennas. MIMO wireless Communication system caused the problems caused by the complexity of the baseband signal processing of geometric growth. Programmable Logic Device following the logic of the existing level is difficult. The condition to achieve the one or veneer all logic algorithms. - Band, the need for the base station platform for a complex interconnect structure
(2) takes time to send the actual data.
System, 4G, baseband physical layer processing, transmission of data between the Node handle real-time high, when you shared the traditional categories of buses. (For example: PCI, CompactPCI, etc.) must have the baseband processor nodes, the quantity of data between the node increases have been absorbed quickly. Interactive and real-time transmission to the device bound to affect performance. Share of traditional architecture, so difficult, the bus system to meet these requirements. Necessary to design a new platform to ensure scalability in a good position to make a connection between the devices on the bus for data transfer latency on a small bus.
(3) flexible and need flexibility.
Current international Standards for the system. 4G is not using an algorithm to process the baseband have been determined. And link-layer protocol inspection is not completed and fully are.

Questions or graphics card?
I'm looking at my computer, here is something to discuss details. Bus Expansion: Bus type: PCI Bus Speed PCI 33MHz PCI Interface: PCI Connector Three Size: 120 legs wide data connector PCI (max.): 32 bit ---------- and then in different parts. : Ports and terminals: external Internet. :: The: - 15 ---------- VIDEO a hole in the plug, and much more. Videos: Video Controller: Integrated Intel Extreme Graphics 3D I have a Dell 2400 Demension I would like to update card spending .. 40-70 dollars of my video. I want to play in the situation. Guild Wars. What do you recommend? Links would be great. Thank you very much for your time.
70. Dollars will get you in the middle of the line graphics card. It should handle Guild Wars is a good link. www.newegg.com watch your video card is integrated on the motherboard, this is something that your video controls. You want to look for cards. PCI slot One example: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=40000048+4026+1069609642&Description=pci+cards&name=PCI. This is what you are looking for. The problem is, your computer is quite outdated.
