WebMay 10, 2016 · I want to send one bit x over a noisy channel, specifically, a binary symmetric channel with error probability p, where p = ( 1 − ϵ) / 2 and ϵ is small. In other words, the error probability is close to 1/2, so the capacity of the channel is small. The obvious method is to use a repetition code: repeat x many times. fosdick masten vocational high schoolWebNov 24, 2016 · Channel Decoding: Gaussian Channel as Time-Varying Binary Symmetric 1 Heuristic explanation of channel capacity for discrete noiseless channels and binary symmetric channel fosdick road carver maWebachieve the capacity of symmetric binary-input discrete memoryless channels such as the binary symmetric channel (BSC) and binary erasure channel (BEC).
