This paper investigates the joint subcarrier and power allocation problem for the downlink of a multi-carrier non-orthogonal multiple access (MC-NOMA) system.

This paper describes the applicability of subcarrier multiplexing to lightwave multiple-access networks.

In this paper we assess the pains and potential gains a wireless communication system can leverage on, if we allow for multiplexing different subcarrier spacings within a single transmission time i

Given an (n x d)-matrix A and an (n x 1)-vector b, the L_1 regression problem is to find the vector x minimizing the objective function ||Ax - b||_1, where ||y||_1 = sum_i |y_i| for vector y.

Adaptive Media Playout (AMP), the adaptive mod- ification of media playback speed, has been previously proposed as a technique to modify the playout delay of a user with respect to other users or w

Recently, broadcasted 3D video content has reached households with the first generation of 3DTV.

The preceding two papers describe the nature of the problems introduced into telephone circuits by delay and echo and the attempted solution of these problems through the design of echo suppressors

"How does it sound?" This is a fundamental but elusive question for the engineer designing or evaluating a system for transmitting, recording, or processing speech signals.

An earlier experiment by Riesz and Klemmer on the effect of puretransmission delay upon natural telephone conversations was extended in a test with more than double the time period and number of ca

The increase of multimedia services delivered over packet- based networks has entailed greater quality expectations of the end-users.
