| dc.description.abstract | 本論文中，我們希望藉由Micro LEDs能夠高速切換亮暗態的特性，設計出一套全新的通訊系統，目前市面上的通訊系統幾乎都是使用無線電波來傳輸資訊，雖然也有以光做為傳輸媒介的論文被發表，但大多數是以雷射光作為輸出端，只有少數的論文是以Micro LEDs作為輸出端，並且都只使用少量光源，藉由調控頻率與振幅來傳遞資訊，尚未有人於實驗中使用大量的光源做為輸出端，因此我們想以此做為突破口，建立一套全新的成像通訊系統。
為了建立一套異於他人的通訊系統，我們首先須針對傳輸資料進行編碼，這也是本團隊在本實驗中最大的創新，我們利用稀疏碼的觀念為基礎，分別建立了以七位元與九位元為基底的編碼圖形，每頁以七位元為基底的編碼圖形可帶有226,802位元的資料量，而每頁以九位元為基底的編碼圖形可帶有291,600位元的資料量。接著本團隊研究出一項較不同的編碼規則，建立了以十四位元為基底的編碼圖形，此圖形為本團隊設計出的最高資料量共含有453,600位元的編碼。
在經過多次實驗後，驗證了所有位元編碼的可行性，並嘗試以不同光學系統來提升傳遞距離，期望能設計出一套可以高速且可遠距離傳輸的通訊系統。 | zh_TW |
| dc.description.abstract | In this thesis, our team hopes to use the fast switching ability of the Micro LEDs display to build a high speed imaging communication system. The communication system on the market now usually transmit data by using the amplitude and frequency of the radio wave. Only few experiments use laser diode or Micro LEDs as the source of the communication system, and the total number of the light sources are usually less than five. Therefore, using the high number of light sources to transmit data is the advantage of our design.
In order to lower the error rate of our communication, we form some special specifications for our coding. Finally, we got three different kinds of coding. The coding graphics based on seven bits and nine bits are established first. The coding graphics based on seven bits per page can contain 226,802 bits of data, and the coding graphics based on nine bits per page can contain 291600 bits of data. Then our team researched a different coding rule and established a coding pattern based on 14 bits, which has the highest data volume coding rule designed by our team and contain 453,600 bits of data per page. After many experiments, three codings were verified and proved that our design is successful . After the feasibility of our design had been proven, we try to improve the transmission distance with different optical systems, hoping to design a set of communication systems that can transmit at high speed and can be transmitted over long distances. | en_US |
