Derive expression for error in z a+b

WebThen, we derive the exact closed-form expression of the average BEP of the ML receiver (2.27) for orthogonal signalling. The average BEP expressions in this subsection are general and functions of σ2e and ¯γb. In Subsection 2.1.5, we will study quasi-static and time-varying channels as two special cases. Webx' = x*a + b and the variance, lets call it s^2, will change to (s^2)' = a *s^2 , So you may notice that the mean is affected by adding a constant b to it, but the variance is not really …
