To mitigate the effects of time-varying fading, Pilot Symbol Assisted Modulation (PSAM) has been introduced in [1], through which the transmitter periodically inserts known symbols or pilots in the data frame. The channel estimates obtained from these pilots are then employed in the coherent demodulation of data symbols. A novel PSAM scheme was introduced(More)
We consider a small-cell cluster consisting of N receive radio-heads connected to a Remote Central Processor (RCP), which jointly decodes K users. Linear filtering across receive antennas is assumed, where the filters are estimated from pilot symbols according to a Least Squares Error (LSE) criterion. Given a limited number of pilot symbols, the Antenna(More)
Time-varying fast fading channels present a major challenge in the design of wireless communication systems. Pilot Symbol Assisted Modulation (PSAM) has been introduced to mitigate the effects of fading and allow coherent demodulation. Our work studies the performance of non-feedback adaptive PSAM scheme over time-varying Rayleigh fading channels. A modular(More)
—We address the problem of uplink cooperative reception with constraints on both backhaul bandwidth and the receiver aperture, or number of antenna signals that can be processed. The problem is cast as a network utility (weighted sum rate) maximization subject to computational complexity and architectural bandwidth sharing constraints. We show that a(More)
We study the continuous frequency spectrum management problem for the two-user Gaussian interference channel. We consider a successive interference cancellation scheme between the two receivers. In this model, receiver 1 decodes user 1 and passes the decoded bits to receiver 2 which in turn cancels the interference from user 1. We analytically determine the(More)
