An Iterative MIMO-HSDPA Receiver Based On a K-Best-MAP Algorithm
— We propose an iterative receiver for horizontally encoded MIMO systems like the PARC proposal for MIMOHSDPA. Our receiver uses a K-best-MAP demodulator to provide the channel d...

Efficient Construction of Weakly-Connected Dominating Set for Clustering Wireless Ad Hoc Networks
In most of the proposed clustering algorithms for wireless ad hoc networks, the cluster-heads form a dominating set in the network topology. A variant of dominating set which is mo...
