Technique for analysing error probability of π/2-wedge-shaped decision region
Hua Fu, Kwok Hung Li, Pooi‐Yuen Kam · Electronics Letters · 2005
A new approach for analysing the error probability of a signal constellation that involves a π/2-radian, wedge-shaped decision in additive white Gaussian noise is presented. The result is obtained in exact closed-form in terms of the Q-function. Applied to 8-QAM, this approach gives an exact closed-form expression for the symbol error probability.
