AbstractFor a narrowband flat-fading channel taking into account Ricean K-factor, spatial fading correlation, and gain imbalances, we derive analytic expressions for the outage capacity of space-time block codes. Our results are then used to study the impact of these propagation parameters on the outage capacity of space-time block codes. Furthermore, we introduce an outage capacity motivated measure of diversity gain which reveals that the diversity gain offered by space-time fading channels depends strongly on the outage rate and propagation conditions. Finally, we verify the accuracy of our analytic results through comparison with numerically obtained results
KeywordsSpace-time block codes, outage capacity, channel modeling, diversity gain
