* Question
| What are the channel interferences that degrade performance? |
* Answer
| (1) In the case of a specific model of the frequency selective channel and the power line channel, the non-coherent demodulation of the maximum envelope detection is not optimal.
(2) Narrowband noise can cause a large envelope, and an error occurs at the output of the demodulator. (3) Impulse noise has a broadband characteristic, which may result in multiplication of large envelopes. |
