Abstract

This paper presents a multipacket detection technique for dealing with packet collisions in OFDM schemes (Orthogonal Frequency Division Multiplexing). Instead of discarding collided packets as it is done in traditional MAC approaches (Medium Access Control) additional packets are transmitted and separated using Multiple Input Multiple Output (MIMO) based techniques. Reliable detection and high throughputs can be achieved as long as different interleavers are used for different retransmissions. We also include a method for estimating the users involved in the collision.
