It turns out that the capacity (even in this simple case) has no closed form. I report from "Modern Coding Theory" by Richardson and Urbanke: C BI-AWGN = 1 + 1 ln ( 2) ( ( 2 N − 1) Q ( 1 N) − 2 π N e − 1 2 N + ∑ i = 1 ∞ ( − 1) i i ( i + 1) e 2 i ( i + 1) N Q ( 1 + 2 i N)) WebWireless communication at sea is an essential way to establish a smart ocean. In the communication system, however, signals are affected by the carrier frequency offset (CFO), which results from the Doppler effect and crystal frequency offset. The offset deteriorates the demodulation performance of the communication system. The conventional Gardner bit … chuck versus the beefcake cast
