VHDL是Very High Speed Integrated Circuit Hardware Description Language的缩写, 意思是超高速集成电路硬件描述语言。对于复杂的数字系统的设计,它有独特的作用。它的硬件描述能力强,能轻易的描述出硬件的结构和功能。这种语言的应用至少意味着两种重大的改变:电路的设计竟然可以通过文字描述的方式完成;电子电路可以当作文件一样来存储。随着现代技术的发展,这种语言的效益与作用日益明显,每年均能够以超过30%的速度快速成长。 这次毕业设计的内容是在简要介绍了VHDL语言的一些基本语法和概念后,进一步应用VHDL,在MAX+plusII 的环境下设计一个电子钟,最后通过仿真出时序图实现预定功能。电子钟的时间显示用到了七段数码管(或称七段显示器)的电路设计,内部的时间控制输出则用到了各种设计,包括:加法计数器,扫描电路,控制秒、分、时的分频电路,各种数制的转换。

基于OFDM的无线宽带系统仿真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.
