Capacity in awgn channel
WebJan 25, 2014 · So if we take the familiar voice grade telephone channel with 35 dB SNR and 3000 Hz BW, we find the AWGN capacity C is about 34.8 kbps which is a familiar number. To get from there to bits/symbol we divide by the symbol rate, which must be something close to 3000 giving 11 bits/symbol. $\endgroup$ The notion of channel capacity has been central to the development of modern wireline and wireless communication systems, with the advent of novel error correction coding mechanisms that have resulted in achieving performance very close to the limits promised by channel capacity.

The theory of linear block codes, decoding techniques using soft-decisions and hard-decisions, and their performance simulations. * Monte Carlo simulation for ascertaining performance of digital modulation techniques in AWGN and fading channels - Eb/N0 Vs BER curves. Pulse WebThe channel then appears to the encoder and decoder as a time-invariant AWGN channel. This power adaptation is called channel inversion. Fading channel capacity with channel inversion is just the capacity of an AWGN channel with constant SNR σ C = B log 2 [1 + σ] What is the advantage and disadvantage of this scheme?.
