Description: Linsim is designed to read and then add path simulation to any monophonic wav file recorded at any sampling rate. It works particularly well with files that were created using fldigi’s audio capture and audio generate functions. The entire wav file will be saved to computer memory and then duplicated during the signal processing. The user should try to keep the length of the wav file at 20 Mg or less, but the author has tested some 200 Mg files on both Linux and Windows-8 without causing a program fault. These files were original VOAR broadcasts of about 30 minutes duration. The objective of this type of simulation is to finally measure the character error rate (CER) and bit error rate (BER) of a specific modem type and decoder design. For most modems a sequence of 1000 characters provides a sufficient level of confidence in the CER measurment.
