Affine Grassmann codes
We consider a new class of linear codes, called affine Grassmann codes. These can be viewed as a variant of generalized Reed-Muller codes and are closely related to Grassmann codes...

Exponential bounds implying construction of compressed sensing matrices, error-correcting codes, and neighborly polytopes by ran
In [12] the authors proved an asymptotic sampling theorem for sparse signals, showing that n random measurements permit to reconstruct an N-vector having k nonzeros provided n >...

Multiple-Input Multiple-Output Gaussian Broadcast Channels With Common and Confidential Messages
This paper considers the problem of the multiple-input multiple-output (MIMO) Gaussian broadcast channel with two receivers (receivers 1 and 2) and two messages: a common message ...

Random access in wireless networks with overlapping cells
We study cellular-like wireless networks in which the cells may overlap substantially, and a common channel is used for all cells. Thus, transmissions intended for one destination ...

Optical orthogonal signature pattern codes with maximum collision parameter 2 and weight 4
An optical orthogonal signature pattern code (OOSPC) finds application in transmitting 2-dimensional images through multicore fiber in code-division multiple-access (CDMA) communic...

Codes for deletion and insertion channels with segmented errors
Abstract-- We consider deletion channels and insertion channels under an additional segmentation assumption: the input consists of disjoint segments of b consecutive bits, with at ...

Target detection via network filtering
A method of `network filtering' has been proposed recently to detect the effects of certain external perturbations on the interacting members in a network. However, with larg...
