Non-Uniform Constellations for ATSC 3.0
This paper introduces the concept of a non-uniform constellation (NUC) in contrast to conventional uniform quadrature-amplitude modulation (QAM) constellations, and considers different kinds of NUCs and describe their performance. Expand
Combined MMSE equalization and blind parallel interference cancellation for downlink multirate CDMA communications
A new reception scheme suitable for multirate systems (with different spreading codes) is proposed, which is compared with equalization and IIC alone, and practical issues when implementing this receiver are discussed. Expand
High order non-uniform constellations for broadcasting UHDTV
This paper investigates high order NonUniform Constellations (NUC) with constellation sizes of up to 4K-QAM for broadcasting over-the-air very high data rate services such as Ultra-High Definition TVExpand
Cooperative multicast resource allocation strategy
The new CoMR strategy is based on an efficient one-to-many resource sharing technique which exploits the space diversity of the two hop topology and showed considerable enhancement of both system throughput and user fairness and noticeable improvement in terms of energy efficiency compared to the non-cooperative multicast scheme.

Improving the DVB-T2 BICM performance by newly optimized Two-Dimensional Non-Uniform Constellations
A complete analysis of the DVB-T2 system performance when using the proposed 2D-NUQAM constellations against regular uniform (M-QAM) is presented. Expand
Joint detection and channel estimation for broadcast OFDM systems using hybrid Zadoff Chu pilots
The proposed hybrid Zadoff-Chu (ZC) based pilot sequence suitable for OFDM broadcast systems can be used as a design basis for future broadcast systems to build on, where a separate preamble will no longer be needed, thus, reducing the frame overhead. Expand
Roads to Multimedia Broadcast Multicast Services in 5G New Radio
This work analyzes the use of a mixed mode that shares multicast, broadcast and unicast resources via the same physical channel, providing an objective insight roads to MBMS provision in 5G NR. Expand
Physical Layer Performance Evaluation of LTE-Advanced Pro Broadcast and ATSC 3.0 Systems
It is observed that ATSC 3.0 outperforms both eMBMS solutions, i.e., MBMS over Single Frequency Networks (MBSFN) and Single-Cell PTM (SC-PTM) in terms of spectral efficiency, peak data rate and mobility, among others. Expand
On the Ergodic Capacity of Frequency Selective MIMO Systems Equipped with MMSE Receivers: An Asymptotic Approach
The main results of the paper are related to the design of an optimal precoder in the case where the transmit antennas are correlated and it is shown that the left singular eigenvectors of the optimum precoder coincide with the eigenvalues of the mean of the channel taps transmit covariance matrices.

Asymptotic Analysis of Reduced-Rank Chip-Level MMSE Equalizers in the Downlink of CDMA Systems
This paper addresses the performance of downlink CDMA receivers that consist in a reduced rank Wiener chip-rate equalizer followed by a despreading operation and proves that the asymptotic SINRs converge exponentially to the SINR of the plain Wiener receiver when the rank of the receiver increases.
