Shannon limit on power efficiency – demystified

by

The Shannon power efficiency limit is the limit of a band-limited system irrespective of modulation or coding scheme. It informs us the minimum required energy per bit required at the transmitter for reliable communication. It is also called unconstrained Shannon power efficiency Limit. If we select a particular modulation scheme or an encoding scheme, we … Read more

Shannon channel capacity demystified — AWGN formula, SNR, and the −1.6 dB limit

by

Information theory path: BPSK AWGN → Shannon capacity → Shannon power-efficiency limit → Capacity calculator In one sentence: Shannon capacity is the highest rate (bits per channel use, or bits per second for a continuous-time bandlimited AWGN channel) at which information can be sent with arbitrarily small error probability.  Shannon theorem dictates the maximum … Read more
