“…Similarly, various works [8], [9] addressed MAC-layer performance of ad-hoc networks employing SpU-MIMO techniques and certain slotted ALOHA variants, with varying degrees of link-level interaction. A number of works [10]- [12], and related references therein, employing closed-loop MIMO schemes, focus on achieving multiple simultaneous successful transmissions in an ad-hoc network assuming that all the H D s and H i s (as per Fig. 1) are known to all the users/nodes for appropriate precoding and interference cancellation.…”
