No FEC in basic_tx,rx

There is no forward error correction scheme(FEC) in the basic_tx , baisc_rx scripts, just a crc check.

Hence don't expects a replicated output at the receiver just like that.

Many newbies just select the --from-file option while transmitting a jpeg, mp3 file and expect the same file at the receiver :)

One need to include their own FEC if they want less errors in the received packets.

In the program which implements tcp-ip there is some sort of error correction technique because it uses tcp-ip and hence you can get the file at the receiver without any error
