Abstract :
The bit error probability for binary modulation and multiple correlated Rayleigh fading diversity branches is derived. The receiver performs maximum ratio combining of the diversity branches based on noisy channel estimates. Our results provide new analytical insights into performance, design, and optimization of some known communication receivers.
