Opportunistic Joint Decoding With Scheduling and Power Allocation in OFDMA Femtocell Networks
Source: University of Toledo
One of the major challenges in deploying femtocells is the management of interference between neighboring femtocells and between the femtocells and the macrocells. This paper explores the use of opportunistic multiuser detection for interference mitigation in the downlink of an Orthogonal Frequency Division Multiple Access (OFDMA) femtocell network. In particular, the authors focus on the use of Joint Decoding (JD) at the receiver, where a macro or femto user may jointly decode both the desired message and the message from a selected interfering user in order to achieve a higher overall transmission rate.
