Image Coding Using Dual-Tree Discrete Wavelet Transform
In this paper, we explore the application of 2-D dual-tree discrete wavelet transform (DDWT), which is a directional and redundant transform, for image coding. Three methods for sp...

Diversity Analysis of coded SVD Schemes for MIMO Spatial Multiplexing Systems
— When channel state information (CSI) is available at both transmit and receive sides, singular value decomposition (SVD) converts the MIMO channel into parallel subchannels. It...

Coding Theorems on the Threshold Scheme for a General Source
In this paper, coding theorems on the (t; m)-threshold scheme for a general source are discussed, where m means the number of the shares and t means a threshold. The (t; m)-thresho...

Design Tradeoffs and Hardware Architecture for Real-Time Iterative MIMO Detection using Sphere Decoding and LDPC Coding
Abstract-- We explore the performance and hardware complexity tradeoffs associated with performing iterative multipleinput multiple-output (MIMO) detection using a sphere decoder a...

Coded multipulse pulse-position modulation for free-space optical communications
—In this letter, we address two questions concerning the application of multipulse pulse-position modulation (MPPM) for free-space optical (FSO) communications: (1) under what co...
