Through reading familiar with the use of system object in MATLAB, and on this basis to build a communication system based on sound card. Among them_ TX is run by the sending computer_ RX or_ Scope is the synchronous operation of the receiving computer. Source code wave_ Scope. M and WGN_ Tx.m completed (1. Measure the channel characteristics of "audio line channel" and "acoustic channel") According to the above channel characteristics, select the appropriate system structure and determine the system parameters, and simulate the BER curve of the system. In AWGN channel, the BER of the system should be PE 10 & lt; = 3 (@ EB / N0 = 6dB), and the transmission rate should be as high as possible Source code BPSK_ Tx.m and BPSK_ Rx. M completed (3. According to the above system parameters, build a communication system based on sound card, realize the information transmission of two different computers through the audio line, and verify the correctness of the information transmission.) Source code BPSK_ Tx.m and BPSK_ Rx. M completed (4. Two different computers through the "sound wave" for information transmission, and verify the correctness of information transmission.)
