<? Pub Dtl=""?> In a multiple-antenna system with two transmitters and two receivers, a
scenario of data communication, known as the X channel, is studied in which each receiver …

In this article we consider network coordination as a means to provide spectrally efficient
communications in cellular downlink systems. When network coordination is employed, all …

multiple antennas using two or more spaced independent antennas at the transmitting …

A clustered base transceiver station (BTS) coordination strategy is proposed for a large
cellular MIMO network, which includes full intra-cluster coordination-to enhance the sum rate …

A system and method are described which enable planned evolution and obsolescence of
multiuser wireless spectrum. One embodiment of such a system includes one or multiple …

Multi-antenna transmission and reception (known as MIMO) is widely touted as the key
technology for enabling wireless broadband services, whose widespread success will …

Intercell interference limits the capacity of wireless networks. To mitigate this interference we
explore coherently coordinated transmission (CCT) from multiple base stations to each user …

The sum-rate capacity of a cellular system model is analyzed, considering the uplink and
downlink channels, while addressing both nonfading and flat-fading channels. The focus is …

A new structure for multi-base systems is studied in which each user receives data from two
nearby base stations, rather than only from the strongest one. This system can be …

Cooperative transmission by base stations (BSs) can significantly improve the spectral
efficiency of multiuser, multi-cell, multiple input multiple output (MIMO) systems. We show …
