It is divided into 25 floors of the main building and 4 floors of the podium building, with a building height of 86 meters.

Fortunately, with the progress of technology and the improvement of computing power, the hardware problem of LDPC code has been alleviated, It has become a 5g standard data channel code (the control channel is the polar code mainly promoted by Huawei.
The building can be seen from the JR bullet train running on the nearby railway.
The installed capacity is 300kW and the annual power generation is 280000 kW · H (refer to: the annual power consumption of a family of three is about 2400kw · h).

Sanyo solar ark is an enterprise partner of the 2005 Aichi World Expo in Japan.
The facility is 315 meters wide and 37 meters high.
The photovoltaic building integration technology (BIPV) to be introduced in this paper is not so lucky.
It covers an area of 260000 square meters.
In our daily life, we see that most of the solar systems on the roof are bapv, that is, building applied photovoltaic.
The fully parallel decoding structure consumes a lot of hardware resources.
From the literal meaning of “integration”, we can know that BIPV is a photovoltaic technology that must be considered in the design stage.
The difference between bapv and BIPV is that bapv is a solar photovoltaic power generation system attached to the building.
It can still be decoded effectively when the code length is long, The performance is close to the Shannon limit (the maximum transmission rate of error free transmission on the channel with random bit error).
The solar ark contains 5046 panels, generating about 530000 kW · h per year and the maximum system power is 630kw.
It is one of the largest solar buildings in the world..
Why on earth? Building integrated photovoltaic (BIPV) is to replace the traditional building envelope with photovoltaic materials, such as roof, skylight and facade, so as to make it a part of the building.
Apple’s new headquarters is currently the world’s largest completed BIPV project.
Designed by jobs during his lifetime, it is located in Cupertino, California.
This code has the advantages of flexible structure, low difference error code and supporting parallel operation.
Its solar power generation has reached an amazing 17MW, which can meet 75% of its power demand.
From being proposed in 1963 to being officially listed as a standard in 2017, LDPC code has finally stepped on the main stage after a long history of nearly half a century.
BIPV was first produced by Japan’s mingsaka vacuum Co., Ltd.
(MSK, Japan, acquired by Wuxi Suntech in 2008) in 1968.
It can be said that LDPC coding is almost perfect channel coding, but why not as the main channel coding of communication at that time? The main reason is that it depends on hardware performance.
The building took eight years to complete, with a total cost of $5 billion, and was put into use in 2017.
The installed capacity of diangu Plaza / business conference center supporting the functions of the hotel is 500kW and the annual power generation is 420000 kW · H.
At that time, I chose LDPC code that has not officially become 5g standard.
BIPV can generate electricity, and as a part of the building, it undertakes the functions of wind and rain protection, waterproof, heat insulation, sound insulation, structural stress, beauty and so on.
It is usually attached to the building through a simple support structure after the building is completed.
(the estimated power generation capacity of Tesla Nevada super factory is 70mW, but so far it has only reached 3.2mw) (source: Phoenix) (source: John martellaro) Baoding power Valley International Hotel project.
LDPC code, fully known as low density parity check code, was proposed by Robert Gallager of MIT in his doctoral thesis in 1963.
The construction started on November 5, 2007 and officially opened on October 18, 2008.
The teacher asked the students in the class to prepare materials interested in communication for reading, sort them into PPT and share them in class.
It is located in Yudao City, Gifu Prefecture, the geographical center of Japan.
The building area is 41300 square meters, covering an area of 62 mu.
It is located in the core of Baoding “China Electric Valley” and invested and constructed by Yingli group.
The power generation is directly connected to the State Grid, which can save 104 tons of standard coal, reduce 270 tons of carbon dioxide emission, 2.3 tons of sulfur dioxide emission and 1 ton of nitrogen oxide emission throughout the year.
Its main function is power generation and does not undertake the function of the building itself.
If the photovoltaic modules are removed later, the building function will not be affected.
Friends who know a little about the communication history should react that the promoter of LDPC code is Qualcomm, which also derives the legend “voting gate” in the Jianghu Event, Lenovo does have some operations in the series voting of data channel coding and control channel coding, but it is not the key to the defeat of polar code in data channel coding compared with LDPC code).
Although the world record of the world’s largest BIPV under construction / completed project is constantly refreshed at home and abroad, and some media have been speculating about the news of the development of BIPV at that time all the year round, BIPV is still in a feeling of just passing the midfield.
Introduction there was a course in the school when I was in graduate school.
Baoding Electric Valley International Hotel is the world’s first five-star BIPV hotel with solar power generation system.
