设计Arduino的销13被连接到220欧姆的电阻。连接到晶体管2N222A电阻，然后连接到基座。一条腿被连接到地，另一条腿被连接到蜂鸣器。此外蜂鸣器连接到Vcc。蜂鸣器，请12伏变为5伏。

C program to calculate the BER performance of BPSK modulation in an AWGN channel. The program takes the file "BPSK" containing voltage levels and passes it in an AWGN channel with a given SNR. The received message is then Hard decision decoded and the bit error rate is calculated. The BER over different SNR is calculated. THe output values can be used to draw a BER vs SNR(dB) curve.

CRC的全称为Cyclic Redundancy Check，中文名称为循环冗余校验。它是一类重要的线性分组码，编码和解码方法简单，检错和纠错能力强，在通信领域广泛地用于实现差错控制-CRC called the Cyclic Redundancy Check, the Chinese name of the Cyclic Redundancy Check. It is an important class of linear block codes, encoding and decoding method is simple, and error detection and correction capability in the field of communication widely used to achieve error control
