# Problem
Students residing in residential colleges at the IZJU campus encounter issues when they inadvertently lock their ID cards inside their dormitories, particularly after showering at night. These students require a temporary IC card that exclusively grants access to their dormitory doors. However, staff availability is limited late at night to issue such IC cards. Consequently, an automated IC card dispenser is necessary to provide temporary IC cards to students.

# Solution Overview
The automated IC card dispenser system will authenticate students’ identities by scanning QR codes on their cell phones. Upon identity verification, the system's embedded software will retrieve the student's dormitory details. Subsequently, the mechanical system will select an IC card, program it with access information, and dispense it. Concurrently, the system will log the borrower's details. Once students return the temporary IC cards, the mechanical system will retrieve them, erase the stored data, and the software will log the cards as returned.

# Solution Components
## KIOSK Software
The software will encompass the user interface (UI), interaction with the central server, and integration with the recycling mechanical system.

## Recycling Mechanical System
The recycling mechanical system will comprise a card storage box, a conveyance system for card transportation from the storage box to the reading and exit points, and an IC card reader/writer.

## Web User Interface
The web user interface will facilitate interactions between users and administrators. Users can authenticate via the interface, while administrators can monitor terminal status and exercise remote control.

## Server System
The backend software will be responsible for user authentication and authorizing the terminal to issue a new card.

# Criteria for Success
Robustness: The system should operate continuously 24x7 without significant issues or maintenance requirements. The recycling system's error rate should not exceed 1/500, and the system must detect errors and notify administrators promptly.

Efficiency: The system should handle user requests swiftly and effectively.

Security: Data transmission between terminals and the server must be secure and resistant to prevalent hacking techniques.

Compatibility: The system should be compatible with existing authorization and access control systems.

PROJECT NAME: A Direct Digitally Modulated Wireless Communication System

PROBLEM: Communication system is closely related to our life. We measure communication systems primarily by their effectiveness and reliability. But in fact, validity and reliability are a pair of contradictory indicators, and they need a certain compromise. We hope to improve the efficiency of communication system on the basis of guaranteeing the accuracy of communication.

SOLUTION OVERVIEW: The project is to design and implement a kind of communication system for the next generation technology which is much more simplified compared to the systems that existed. The final version of the system should be expected to be able to transmit data like images and videos.

Our basic idea is that the information can be send in digital signal form to matesurface, EM waves will be sent to the matesurface and be scattered to space. The information we want to transit will be carried on scattered EM waves. And once the receiver receives the signal it will be decoded into the original information.

Basically, our project is a kind of innovation or re-creation of an existing communication system. The biggest difference between our design and other systems could be the method to process the information. There is a significant component in our future design called metasurface, which could be used to adjust the phase, magnitude, and polarization along with other significant properties of EM waves which can send multi-digit signal at same time.

As for the functionality of our project, we think it could be an interesting trial and we have faith to finish it since everything we need in the project we could find plenty of research materials and reports to look into. Even if the project is not applicable in the end, we believe the application of the metasurface material could be still powerful in communication system.

SOLUTION COMPONENTS: Metasurface: it could be used to adjust the phase, magnitude, and polarization along with other significant properties of EM waves. Receiver: it is where information will be received and decoded. FPGA: it is where information will be prepared and send to the metasurface. Signal emitter: Send EM wave to matesurface.

CRITERION FOR SUCCESS 1.The system could be used to transmit data like Images and Videos. 2.The system should be able to demonstrate a certain level of supreme communication efficiency
