WebJul 7, 2024 · What is AWGN channel capacity? The AWGN capacity formula (5.8) can be used to identify the roles of the key resources of power and bandwidth. This formula measures the maximum achievable spectral efficiency through the AWGN channel as a function of the SNR. WebFeb 17, 2024 · S1: Channel capacity is the same for two binary symmetric channels with transition probabilities as 0.1 and 0.9. S2: For a binary symmetric channel with transition probability 0.5, the channel capacity is 1. S3: For AWGN channel with infinite bandwidth, channel capacity is also infinite. S4: If Y = g(X), then H(Y) > H(X).
