VHDL是Very High Speed Integrated Circuit Hardware Description Language的縮寫, 意思是超高速集成電路硬件描述語言。對于復雜的數字系統的設計,它有獨特的作用。它的硬件描述能力強,能輕易的描述出硬件的結構和功能。這種語言的應用至少意味著兩種重大的改變:電路的設計竟然可以通過文字描述的方式完成;電子電路可以當作文件一樣來存儲。隨著現代技術的發展,這種語言的效益與作用日益明顯,每年均能夠以超過30%的速度快速成長。 這次畢業設計的內容是在簡要介紹了VHDL語言的一些基本語法和概念后,進一步應用VHDL,在MAX+plusII 的環境下設計一個電子鐘,最后通過仿真出時序圖實現預定功能。電子鐘的時間顯示用到了七段數碼管(或稱七段顯示器)的電路設計,內部的時間控制輸出則用到了各種設計,包括:加法計數器,掃描電路,控制秒、分、時的分頻電路,各種數制的轉換。

基于OFDM的無線寬帶系統仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.
