WebJun 20, 2024 · In practical wireless communication systems, wireless fading channels are susceptible to noise, interference, and other channel factors, which can lead to serious challenges for reliable communication. Therefore, research on fading channels is of great practical significance.
Webinstantaneous channel conditions. In the latter case, some traffic must be discarded when interference causes reductions in data rate, leading to buffer overflows. FIGURE 1 Example SNR for 1 × 10-4 BER in fading channel*, ** SNR (dB) vs. data rate (bit/s) * Two independent equal average power Rayleigh fading paths, with a fixed movement for the ordination of women sydneyWebIt is the measure of the speed at which channel characteristics change. This determines the rate at which fading occurs. When the channel changes are higher than the modulated symbol rate, fast fading occurs. Slow fading occurs when the channel changes are slower than the symbol rate.
