Processing and transmission of voice information remains actual scientific problem. In this article, authors developed a computer model of voice messages transfer through a wireless communication channel. The major issues of the article are implemented as a computational model that can be used to design wireless systems. To transmit a signal the following types of modulation were used: QAM-16, QAM-64, BPSK and QPSK, a dependence between BER parameter and SNR were calculated and compared with theoretical values.References
