Mobile radio window random-access algorithm with diversity

We consider a mobile radio random-access algorithm equipped with a choice of three distinct antenna diversity plans (two-fold, maximum selection, or ideal selection diversity) to improve the performance. The algorithm is stable with high throughput and low delays. The mobile environment is regulated by the presence of multipath fading, shadowing, and path loss. The capture model is a threshold model based on the signal-to-interference ratio. The maximum throughput and optimal window size of the algorithm are analytically computed. The delay performance is evaluated through simulations, and significant improvement is demonstrated over slotted ALOHA under various mobile scenarios.
