Dear Sang Hyuk Kim,
what "packet decoding" are you specifically talking about, and could you show us the code you've modified?
Best regards,
Marcus

Hi, I transmit simple text file using two USRP N210
Tx)file source -> packet encoding -> mod(GMSK) -> usrp sink
Rx)usrp source -> demod(GMSK) -> packet decoding -> file sink
To make corrupt packet, I tried to modify part of crc check
I guess if the crc of received packet doesn't match with original one, receiver would discard the packet.
However, I found receiver accepts every packet even if crc check returns 'false'.(I expected receiver accepts packet only pass crc check by 'true')
Why it always return false and how can I corrupt packet with other ways ?
