A New Analysis of the DS-CDMA Cellular Uplink Under Spatial Constraints
Don Torrieri, Matthew C. Valenti, Salvatore Talarico
A new analysis is presented for the direct-sequence code-division multiple access (DS-CDMA) cellular uplink. For a given network topology, closed-form expressions are found for the…
Exclusion and Guard Zones in DC-CDMA Ad Hoc Networks
Don Torrieri, Matthew C. Valenti
The central issue in direct-sequence code-division multiple-access (DS-CDMA) ad hoc networks is the prevention of a near-far problem. This paper considers two types of guard zones…
An Iterative Noncoherent Relay Receiver for the Two-way Relay Channel
Terry Ferrett, Matthew C. Valenti, Don Torrieri
Physical-layer network coding improves the throughput of the two-way relay channel by allowing multiple source terminals to transmit simultaneously to the relay. However, it is gen…
Closing the Gap to the Capacity of APSK: Constellation Shaping and Degree Distributions
Xingyu Xiang, Matthew C. Valenti
Constellation shaping is an energy-efficient strategy involving the transmission of lower-energy signals more frequently than higher-energy signals. Previous work has shown that sh…
A New Analysis of the DS-CDMA Cellular Downlink Under Spatial Constraints
Matthew C. Valenti, Don Torrieri, Salvatore Talarico
The direct-sequence code-division multiple access (DS-CDMA) cellular downlink is modeled by a constrained random spatial model involving a fixed number of base stations placed over…
Distributed Estimation of a Parametric Field Using Sparse Noisy Data
Natalia A. Schmid, Marwan Alkhweldi, Matthew C. Valenti
The problem of distributed estimation of a parametric physical field is stated as a maximum likelihood estimation problem. Sensor observations are distorted by additive white Gauss…
