On perfect channel identifiability of semiblind ML detection of orthogonal space-time block coded OFDM
This paper considers maximum-likelihood (ML) detection of orthogonal space-time block coded OFDM (OSTBC-OFDM) systems without channel state information. Our previous work has show...

Network Coding Does Not Change the Multicast throughput Order of Wireless Ad Hoc Networks
We demonstrate that the gain attained by network coding (NC) on the multicast capacity of random wireless ad hoc networks is bounded by a constant factor. We consider a network wit...

Highly-parallelized motion estimation for Scalable Video Coding
In this paper, we discuss the design of a highly-parallel motion estimator for real-time Scalable Video Coding (SVC). In an SVC, motion is commonly estimated bidirectionally and o...

Query-Efficient Locally Decodable Codes of Subexponential Length
A k-query locally decodable code (LDC) C : n N encodes each message x into a codeword C(x) such that each symbol of x can be probabilistically recovered by querying only k coordina...
