Multiuser and Spatial Diversity in OFDM Systems with Co-channel Interference
Pp. 278-302 (25)
Orthogonal frequency division multiple access (OFDMA) becomes a popular framework of future cellular systems such as 3GPP LTE and IEEE 802.16e WiMAX. Spatial diversity and multiuser diversity are expected to play a key role in future OFDMA based cellular systems. Considering that cellular systems will operate in an interferencelimited environment, it is required to understand the effect of co-channel interference on spatial and multiuser diversity. This chapter highlights the effects of co-channel interference on spatial and multiuser diversity and provides insights into the interactions between multiuser diversity and spatial diversity in the presence of co-channel interference.
