hello SHRIHARSHA, If your simulation looks good, try and see what's different about the incoming signal on air as opposed to the simulation. Is the frequency offset maybe too large? Is the received amplitude correct? Try mapping these into your simulation and see where things start to fall apart. At this point, you seem to have the basic setup correct and just need to continue to experiment with the settings. The packet decoder will work pefectly if the input signal of the demodulator is good enough. The sample rate is also an issue, you should find the best value for your application. Zakaria
