Slow fading channel
Webb11 sep. 2024 · What are the different types of wireless fading? Based on doppler spread there are two types of fading viz. fast fading and slow fading. These doppler spread … WebbAbstract: When a transmitted signal encounters slow fading and the support of the fading gain contains zero, an outage event will happen inevitably, if the transmitter has no knowledge of the channel state. This will deteriorate the system performance metrics such as latency due to re-transmissions caused by the outages. For scenarios like this, we use …

WebbI wish to include also the slow fading part into the expression above. In dB scale the mean and standard deviation of the slow fading is given to be μ d B = 0 dB and σ d B = 5 dB, respectively. I believe the new expression can be written as A = P ⋅ X 2 ( V + i W) where X = e Y = e ( μ d B + σ d B Z) / 10 = e σ d B Z / 10 and Z ∼ C N ( 0, 1). WebbFlat or frequency-selective fading: Depending on the values of these above parameters and how they compare to the speed of transmitted symbol, the wireless channel will have flat …
