WebAug 25, 2016 · $\begingroup$ @justin It does make sense: if the channel amplifies the signal 40 times and then add noise, the noise will have to be very powerful in order to be able to introduce any errors! In other words, the SNR at the matched filter will be huge. However, in practice the channel gain is always very small. For a wireless channel, the … WebWireless communication at sea is an essential way to establish a smart ocean. In the communication system, however, signals are affected by the carrier frequency offset (CFO), which results from the Doppler effect and crystal frequency offset.
