(v) Explain what is meant by coherent detection and draw a block diagram of a coherent BPSK receiver. WebbAs you can see by the formulas, a conditional mean is calculated much like a mean is, except you replace the probability mass function with a conditional probability mass function. And, a conditional variance is calculated much like a variance is, except you replace the probability mass function with a conditional probability mass function.
