一个主要的数据通信的当务之急是有效的控制所造成的信道noiseso以使无误差数据检索传输错误。与此目的考虑，severalschemes已开发并用于改善providedto接收机信息的准确性。其中一个方案是电信介质具有alimited带宽。后的源编码而来的信道encoding.As对于信道编码器，该策略是添加冗余到thetransmitted信号，使得在传输过程中所造成的噪声误差可以becorrected在接收机。由于时间不够，我们无法包括channelencoding在我们的研究中。由于错误检查是必需的，其他位可以beappended的数据。它允许接收机以验证到达的informationthat正确与否。一个错误检查的最常用的方法是CRC这是我们在这个项目中所采用的方法。如果有ISNO错误，该信息被假定无差错。否则，retransmissionof相同数据是必需的。这一过程的进一步解释areprovided在下面的章节。datatransmission的性能使用的BER（误码率），其是ofbit误差的studiedtime间隔期间由传送的比特的总数除以数量来衡量。由于BER为信噪比（信噪比）的函数，thisproperty用在这个项目中绘制的误码率超过瑞利衰落信道的曲线BPSKmodulation及以下的AWGN给出。
