Our simulation supports two kinds of source data, either the randomly produced data or an image file. While random data is ideal to test the channel impact to the BER performance and signal constellation, image file give us an intuitive impression and comparison for different channels.
After the source data is produced, the pilot data is inserted into head of source data in each coherence time. It is used to estimate the random phase shift of the fading channel and train the decision to adjust the received signal with phase recover. User may set any percentage of the pilot data length to the total data length (pilot data plus sour
