Mobile communicationhas become an important part of our daily lives for voice communication, datasharing and access over the Internet. Mobile communication is an open network,so maintaining the privacy and reliability of data has always been anxiety. Thereliability of the data against channel noise can be achieved by various errorcorrection codes. The primary purpose of the channel coding process is toreduce the effect of disturbing influences to the minimum level. In this way,the receiver will be able to receive the data sent by the transmitter with theminimum error. In this research paper, it is required to acquire two audiosignals with 8 bits of resolution and 8 kHz sampling frequency for 5 seconds inMATLAB. In the first part of this study, Reed-Solomon (RS) Coding Method wasused to transmit two audio data recorded in .wav format with minimum error.Binary Phase Shift Keying (BPSK) modulation was used as the modulationmethod.  The Bit Error Rate (BER)performance curve was plotted and the difference between the original and thereceived signal was observed. According to the BER performance curve, as thesignal to noise ratio increases, less false data is received at the receiver.In the second part of the study, four wavelet transform families at differentlevels were applied to the audio signal, and the performances of these classeswere compared.
