Wireless Story
This blog talks also about an wireless story. I am now preparing one technical paper to submit to an international conference and a journal, subsequently.
Openoffice weblog editing
I'm now starting to use openoffice as a weblog editor. It is hard to edit the documents in weblog directly. I want to publish interesting scientific stories in the Internet. I have the biggest problem to upload my story in the Internet. The problem is my capability of English writing. I think my English is not that bad but at the same time, not that good. However, by recent long run practice, I can now edit the document in English as much as the native can understand it.
Complexity Mobile Networking
If we allow full mobile ad-hoc networking without any coordination, the interference among different mobiles will be serious. Then, almost nobody can communicate with any other terminals. The current wireless communication systems are coordinated by the centralized access pointer to avoid interuser signal interference. The access pointer makes the signals transmitted by the different mobiles orthogonal to each other so as not to generate interuser interference. We predict that the future mobile neetworking systems will not have a heavy network coordinator. When there is no coordinator, one possible solution to avoid the interference is to use beamforming arrays at terminals where beamforming can effectively suppress transmit and receive interference. For accurate beamforming with high perforamnce interference suppressing requires many antennas which are not practical in real situation because many antennas increase the installation cost such as RF price and device size limitation.
About Green technology blog
This blog discusses green technology for radio access networks. Recently, mobile phones are including many digital functionalities such as enjoying mobile web services and playing music and video multimedia. This results in naturally increasing energy consumption of mobile phones so we wanna talk about this problems.
