On Capacity Under Received-Signal Constraints

نویسنده

  • Michael Gastpar
چکیده

In a world where different systems have to share the same spectrum, the received (interfering) power may be a more relevant constraint than the maximum transmit power. Motivated by such a spectrum-sharing approach, this paper investigates the behavior of capacity under received-power constraints, modeling for example the maximum interference that one system may inflict on another. The insight of the paper is that while in the point-to-point case, transmit and received-power constraints are largely equivalent, they can lead to quite different conclusions in network cases, including relay networks, multiple access channels with dependent sources and feedback, and collaborative communication scenarios.

Outage Effective Capacity of Buffer-Aided Diamond Relay Systems Using HARQ with Incremental Redundancy

In this paper, transmission over buffer-aided diamond relay systems under statistical quality of service (QoS) constraints is studied. The statistical QoS constraints are imposed as limitations on delay violation probabilities. In the absence of channel state information (CSI) at the transmitter, truncated hybrid automatic repeat request-incremental redundancy (HARQ-IR) is incorporated to make ...

Capacity bounds of spectrum sharing networks with no channel state information

Recently, substantial attention has been paid to improve the spectral efficiency of communication setups using different spectrum sharing techniques. This paper aims to study the capacity of fading spectrum sharing channels in the case where there is no channel state information available at the transmitters and receivers. The channel capacity bounds are obtained under secondary user input powe...

Low SNR Capacity of Fading Channels – MIMO and multipath

Discrete-time noncoherent Rayleigh fading multiple-input multiple-output (MIMO) channels are considered, with no channel state information at either the transmitter or the receiver. The fading is assumed to be correlated in time and independent from antenna to antenna. Peak and average transmit power constraints are imposed, either on the sum over antennas, or on each individual antenna. In bot...

Bandwidth-constrained signature waveforms for maximizing the network capacity of synchronous CDMA systems

Synchronous code-division multiple-access systems where each receiver is a minimum mean-squared-error receiver and each user has the same received power, signaling rate, and required signal-to-interference ratio are considered. Based on the results in [8], the optimal signature waveforms under both fractional out-of-band energy and root-mean-square bandwidth constraints that maximize the networ...

Reception Capacity Through Perfect Domination

The capacity of wireless networks is a classic and important topic of study. Informally, the capacity of a network is simply the total amount of information which it can transfer. In the context of models of wireless radio networks, this has usually meant the total number of point-topoint messages which can be sent or received in one time step. This definition has seen intensive study in recent...
