Relay Station Placement Strategy in IEEE 802.16j WiMAX Networks
Abstract—In this paper, we study the relay station (RS) placement strategy in IEEE 802.16j WiMAX networks. Specifically, the impact of RS placement on IEEE 802.16j network perfo...

New Bounds and Optimal Binary Signature Sets - Part I: Periodic Total Squared Correlation
—We derive new bounds on the periodic (cyclic) total squared correlation (PTSC) of binary antipodal signature sets for any number of signatures K and any signature length L. Opti...

Computational Complexity of Decoding Orthogonal Space-Time Block Codes
— The computational complexity of optimum decoding for an orthogonal space-time block code is quantified. Four equivalent techniques of optimum decoding which have the same comp...

Bit-Interleaved Coded Modulation with Mismatched Decoding Metrics
Bit-interleaved coded modulation (BICM) has become the de facto coding standard for communication systems. Recently, BICM has been cast as a mismatched decoding scheme due to the ...

On the Capacity of WDM Passive Optical Networks
—To lower costs, WDM PONs may share the usage of wavelengths, transmitters, and receivers among ONUs, instead of dedicating the transmission between OLT and each ONU with one ind...

Exploiting Sparse User Activity in Multiuser Detection
—The number of active users in code-division multiple access (CDMA) systems is often much lower than the spreading gain. The present paper exploits fruitfully this a priori infor...

Minimizing Sum-MSE Implies Identical Downlink and Dual Uplink Power Allocations
—Minimizing the sum of mean squared errors using linear transceivers under a sum power constraint in the multiuser downlink is a non-convex problem. Existing algorithms exploit a...
